> Perpendicular recording was later used by Toshiba in 3.5" floppy disks in 1989 to permit 2.88 MB of capacity (ED or extra-high density), but they failed to succeed in the marketplace.
- Lerc 2y agoI think that is something else entirely, unless you consider that to be the expensive writing version. Adding a little capability (in this case permitting finer stepping) and letting software guys figure it out was often the way to great new abilities. I often think about tiny little changes to old hardware that would have been an insignificant cost but added great functionality. Like a 4 bit latch xored with the rgbi output of CGA would have enabled a huge gain in what colour options were available. It would only be a few gates. You would still only have 320x200 in four colours but the colours available wouldn't melt your eyes.
- Tuna-Fish 2y agoNo, this is about increasing bit density inside a track by placing the magnetic domains in a different orientation. The floppy standard failed, but it became the norm in hard disk drives as soon as the patent on the special rwhead that was needed for it expired.
