Welcome to Cassette Futurism Lemmy and Mbin Community.

A place to share and discuss Cassette Futurism: media where the technology closely matches the computers and technology of the 70s and 80s.

Whether it's bright colors and geometric shapes, the tendency towards stark plainness, or the the lack of powerful computers and cell phones, Cassette Futurism includes: Cassettes, ROM chips, CRT displays, computers reminiscent of microcomputers like the Commodore 64, freestanding hi-fi systems, small LCD displays, and other analog technologies.

How far could cassettes have gone if there was no alternative? (self.cassettefuturism)

Let's do a thought experiment.

Let's assume we just never got hard drives to work all that well, head crashes are common and large storage capacities are only possible in servers with incredibly expensive anti vibration setups and what not and there's no way they'd ever work in portable devices. And optical media just didn't work out. Maybe somehow we didn't discover the science in time and the companies working on it just failed or bad management decisions killed off the research into it before anything useful came off of it. And flash storage just never came down in price.

How far could we have pushed cassettes and tape if all the effort that went into other technologies had to be put into cassettes because there simply wasn't a good alternative for data storage. What are the limits of how fast we could move tape in a cassette? How miniaturized would the technology be by now in 2023? I know that there are contemporary tape backup systems with large capacities but there hasn't been any efforts into high speed seek times or making cassettes a viable tiny medium for use as removable media on PDAs or mobile phones.

If we could pack data densely enough and move the tape quickly enough how possible would modern computer tasks like high resolution digital video or image editing be? Assuming that we still had the high speed processors and non-persistent memory of the present but just no other data storage medium aside from magnetic tape.

For inspiration consider that in 1992 we had NT Cassettes that are about as big as an SD card an could store nearly a Gigabyte and in the enterprise LTO-9 tape (released in 2021) stores around 18 TB. So it doesn't sound impossible to have tiny cassettes with a lot of storage if we spend the last 3 decades working on it.

I'm incredibly unqualified to even think about how one might get faster random access times but i was imagining sci-fi solutions like looped tape so that you are always at most 1/2 of the tape length away from the point you want to reach, or the tape equivalent of multi actuator hard drives where there's be multiple independent tapes in one cassette in a sort of RAID style thing but maybe instead of (only) striping data could be stored on multiple tapes in different places to always have one tape that is at a position close to the data you want. Or a system where the same tape has multiple read heads applied to it in distant places.
