    I wish the development team much luck! I worked for years on holographic storage using similar polymers. We found writing the data would change its physical location in the medium, and the physical offset may not be constant. We could always recover the data, but the search algorithm was called far too often killing read performance.

      We use holographic storage and computational technology all of the time. True, the physical nature of the storage medium is problematic for classical data storage and retrieval, but as far as a computational matrix, it actually proves ideal for quantum solutions to problems like classic cryptography and NP hard algorithms. We achieve this through the use of intra-phase encoding, which has the added advantage of making the indexing bit both encodable and addressable either laterally or temporally.

    Tapes are still used in archiving because they have yet higher density than hard drives. The problem with optical/magnetic media is latency of random reads. The main advancements in storage over the last 10 years has been making randomly addressable storage, like SSDs, large enough and cheap enough for consumer use.

      Not really: Tapes deteriorate & are a pain to deal with, & high cap. tape drives have high failure rates & need to be replaced.

    Sabine! I love your content! And finally you have touched on an industry that I was involved in and I have a few comments about this video (most of the time I'm intrigued but don't fully understand what you are talking about!). I implore you to read my comments: I was a software developer for Blu-Ray products for a major studio (I'm under NDA so i'm not sure if I'm able to tell you which one).
    In my opinion optical storage of any size is not coming back due to some inherent disadvantages. But let me explain the background:
    Compact Discs were popular because it delivered Digital quality music to the consumer and high capacity data for installation discs etc for computers. CDs were simply not large enough to play a movie even in SD (Standard Definition)
    DVD could store about 5GB... That was large enough to store a compressed movie in SD. Remember DVDs existed at the same time of the birth of the internet yet DVD was preferred because downloading 5GB was not practical back then... it was more convenient to go to the store and buy a disc. But something VERY important to understand is that the quality of a movie was GREATLY effected by the Variable Bit compression of the media.... there is a profession called a compressionist who artfully adjusts many parameters (mainly the Variable bit rate) in order to create the highest quality movie experience that can fit in 5GB...
    Blu-Ray was introduced and at a minimum a Blu-Ray disc could store 50GB (and Blu-Ray is actually where the layering technology was introduced allowing up to 4 layers so that a Blu-Ray disc could get as large as 200GB.). Blu-Ray was large enough to compress HD (High Definition) and later 4k & HDR. incidentally can you guess what Blu-Ray's secret sauce is? its in the name! Blue lasers have a smaller light wave that DVDs red laser and therefore more data could be stored in the same sized media.
    Now, you might think "Why not create a Gamma Ray disc! The wavelengths are even smaller!" That is true but getting a small nuclear explosion needed to generate gamma rays inside a consumer device turned out to be too challenging.... (ok, i'm joking about gamma ray discs)
    The thing is people prefer Download to own for its convenience. Instead of going to the store and buying a disc, People prefer to watch the same movie online which will be delivered in a handful of GB vs a 200GB Blu-Ray because its easier, however, the download to own movies have a smaller bit budget therefore they are far more compressed (even if they brag being 4k and HDR the real measure of quality is a high bit rate in compression and high bit rate equals more bits that has to be downloaded etc.)
    The other thing is that recording the data (i.e. Burning a disc) has always been a very long process.... hours and hours to burn a 50GB blu-ray... so even though it makes a great archiving product it is just not even close to as convenient as the cloud.
    I think a movie put on a disc that stored a petabyte would be AMAZING but consumers will not favor it over the convenience of deciding he or she wants to see a movie and then watching that movie 30 seconds later without leaving home.

      The unit cells store electric charge. It's basically either
      DRAM: A transistor with a capacitor on one port. The capacitor stores charge that can be read out as current when the transistor is switched on.
      Flash: A field effect transistor with an additional floating gate. On that floating gate charge is stored or removed (via electron tunneling). That charge modifies the threshold voltage needed to tun the transistor on or off.
      What Sabine was thinking of is FeRAM (Ferro Electric RAM). It's similar to DRAM but uses a ferro electric gate. It's faster than Flash and longer lasting however it's storage density is far lower and it's much more expensive.

      If you want security, a password manager, and a means of securing everything:
      Set up a raspberri pi or similar, with a USB connection to your PC that acts as a Keyboard input. What you want is a small program that will, on request, type in the relevant password after you hit a confirmation button (a physical button on the pi). For real fun security - have several books or such as text files on the pi, and have a program pull up the relevant file, and per algorithm enter the words and do replacements based on said algorithm. The way you secure that algorithm is using a physical device you plug into the raspberri pi - and of course, you can always have a physically printed back up put somewhere secure; to the untrained eye it will look like a math formula. No formula, no password - and since you could conceivably back most of this stuff up in plane text the secret sauce to getting your password is all you need. And because of transformations - brute forcing the password is impractical at best.

    At about 1:30. Commercial CDs were actually discs of aluminium mechanically stamped with all the holes representing the binary data in one go. They were only read using a laser. CD-Rs and CD-RWs were read and written (and erased if possible) using lasers, here the medium is a kind of ink I believe. Also, the description of Flash drives at 1:55 isn't right. Information isn't stored in magnetisable cells; instead it's stored as electrons across a transistor's PN junction. Applying a reverse polarity overcurrent causes the electrons to 'permanently' tunnel across the junction causing the transistor to read a 0, but the electrons can be forced to tunnel back using an even higher, current a limited number of times causing the transistors to read 1 again. Modern flash uses multi-level transistor currents for higher density storage, but the principle remains. In any case, it's not magnetic.

      The gameplay could be fit into that size and scale still for the most part.
      What you won't fit in is the hundreds of unique textures, the detail of textures, models, and so on. Basically: As Storage became more abundant, computational power grew exponentially, video games took advantage. This is why for years (basically 90's through till around 2014ish) games visual quality got remarkably better every single year. Realism got better - but if we look back now, every "realistic game" that was incredible for it's time is... dated, like severely. The games that have stood up in their visual look are those that went with a visual style that reflected the limits and capabilities of the time and pushed those to the limit.
      So yes - what have gotten bigger are the art assets - audio, and visual.
      In truth, most modern "Ultra" settings are just a "Lets roast the computer without gaining any real benefit of note". Where as, in the past, the Original Crisis game was literally a pushed to the limits showcase of the CryEngine and, ya, if you didn't have a top end system of the day: Forget it. It's why the entire meme around "will it run crisis" emerged because if a computer could run crisis decently, it was a really good system of the day.
      What a fair number of people have kind of clued into now though, is - a good art style, that will run on the modern toaster equivalent of the past, is actually a far better way to go. For one - a good art style will stand the test of time better, but - and this is key - you can reach a wider audience. If you think about Controller + Mouse and Keyboard when you design the game as well, you can create a really good experience with the user selecting how they play the game to their preference - and that means both console and PC release simultaneously becomes more common. Add in control customization by default and - accessibility becomes better.

      Vinyl is the best for storage, as tapes and CDs both degrade and become unreadable over time. But vinyl has the recurring cost of needle replacement, can't be written to unless you have a vinyl lathe and press, some of the better encodings like the dbx remain proprietary, and last but not least, even Vinyl degrades as you play it, unless you use a laser turntable.

    Dear @Sabine (In the interest of clarity) the CDS/DVDs didn't die because they were superseded by HDs (HDs were there already.. and they always had more capacity than CD/DVDs). CD/DVDs were media storage external to the PCs, and in that sense they were replaced by flash-drives, (or pen drives, or whatever people call them in their respective countries). And (OMG... this one was worse...) a bit is not the same as a byte. A byte is an arrangement of 8 bits.

CD-R came out in 1988 when hard drives were about 40 to 64 MB. It wasn't until about 1995 that computer hard disks passed the 650MB mark. So for about the first decade CDs were bigger than hard disks.

    The problem for me is not the amount of storage in a medium, it is the lentgh of time the medium can reliably store the information. Any regular optical disc for storage (different from commercial audio or video discs) uses dyes that deteriorate over time, somewhere between 10 - 20 years, the same is true for harddisc drives, and it gets worse for thumbdrives, or even tape storage that uses magnetism (LTO) to write the information.
    I therefore switched for any photography, family research, document storage that need to last beyond my lifetime (especially for genealogy) to M-disc, that like the commercially produced entertainment discs burn a physical deformation (pit) into the information layer.

    Correct me if I'm wrong but Flash drives and SSDs don't have magnetized cells. The unit cells store electric charge. It's basically either
    DRAM: A transistor with a capacitor on one port. The capacitor stores charge that can be read out as current when the transistor is switched on.
    Flash: A field effect transistor with an additional floating gate. On that floating gate charge is stored or removed (via electron tunneling). That charge modifies the threshold voltage needed to turn the transistor on or off.
    What you are thinking of is FeRAM (Ferro Electric RAM). It's similar to DRAM but uses a ferro electric gate. It's faster than Flash and longer lasting however its storage density is far lower and it's much more expensive.

    Speed was a huge factor for CD's/DVD's as well. If it takes 4X longer to get the info off these discs than compared to an SSD or HDD, they will likely not be adopted except for companies using them for backups.

    • @formes2388

      CD's stored well are going to hold data just fine. But the cost compared to a Tape Drive is astronomical. And since we already have the infrastructure for secure long term storage of magnetic media - the investment into storing CD's and validating the data etc just isn't worth the investment cost. And for data you are going to use semi-frequently, a pair of data servers with Raid storage arrays validating each-other periodically is so far above what the minimum requirement of most cases is - but is stupidly affordable these days, that you can basically set it and forget it.
      CD Back up just doesn't really make sense. Even if a company were to produce an archival grade set of disks. Same kind of issue 3D-XPoint as a Memory technology had: It's really cool, potentially really efficient, consumer friendly in many ways but... For bulk scale it's too expensive, for speed it's too slow, and for consumers it's just not practical: In other words, it just doesn't have a big enough market; at least for now - improvements in the technology could very well see Resistive memory become faster and more stable, and if they can get the cost of manufacturing to come down far enough it would likely prove more reliable than Magnetic tape.
