Maxell is partnering with another company to bring out a new line of audio cassette tapes
Nevertheless, ferric tapes are ideal for 8-bit home computer tape storage. They would be perfect partners to a C64 Datassette, or for any tape interface you may have used with a VIC-20, Plus/4, ZX Spectrum, Amstrad CPC, MSX, BBC Micro, and so on. The square-ish digital pulses used to encode data to audio (and read it back) are actually in the sweet spot for ferric tape on low-end mechanisms.
My immediate thought is: “you got to be kidding, right?” Not that I have personal experience of such usage, but everything I’ve heard says that they were clunky, slow, unreliable, frustrating, and basically a sheer pain to use as a computer data/program storage medium. Who would want to willingly suffer through those days again?
