per byte it must be some kind of flopy. Just think of a gigabyte worth

though.
maybe half gigabyte ....

.... in addition to the recent mention of the 16+2 track head (i.e.
single head that simultaneously would read/write 16 data tracks while
tracking two servo tracks) ... old email with 16+2 track/head reference

http://www.garlic.com/~lynn/2006s.html#30 Why magnetic drums was/are worse than disks ?
some technology, sort of combination from 2321 datacell and old time
disks with single arm moving between platters. it had several hundred
floppies all rotating on a single (horizontal) shaft. r/w head moved
back&forth along the spindle ... and when the r/w head got into position
at the correct floppy ... shot of compressed air (2321 sort of had
something similar as part of inserting strip back into its bin) would
separate the floppies so the head could be inserted (had sort of leading
thin blade that entered first). there was a problem (i don't believe was
ever resolved) with the floppy material streching because of the
constant spinning (this effort was in the mid-to-late 70s ... after
floppies had been invented in san jose ... but before seeing use in
PCs).
misc. past post mentioning this large number of floppies on single
spinning spindle
