Not sure what answer you're after because there have been three commonly used formats for 3 1/2 inch floppies and each was capable of storing a different amount of information. If we focus on what most people consider the early version, 720 kilobytes, but two later versions held considerably more. As I recall, the next generation held 1440 kilobytes, and the third held 2880 kilobytes. The two most common ones held 720 (called double density) and 1440 kilobytes but I don't remember what term was used for it. As an aside, I still have some floppies around that I ought to throw away because I no longer have a computer that will run them.
Double Sided High Density (HD) 3.5" Diskettes held 1.44MB. HD drives were standard on the IBM PS/2 (Personal Station/2, not to be confused with Sony's PlayStation2 or PS2.) Prior to that the standard 3.5" diskette was double sided, double density, which held 720KB per disk.
single-sided or double-sided? I seem to recall 360K diskettes, and then the 1.2M version once the narrow write head came info being. My Epson machine had 1.2M drives in 1989 :)

ReplyDelete1.44 megabytes. Seems an impossibly small amount of data now.

ReplyDelete44Kb. It really doesn't seem that long ago that I had one I would take to school to save my work on!

ReplyDeleteoh man...was that 500K?
ReplyDeleteIt was different between Apple and Commodore and IBM PCs and TRS80s. I hope that's the right number.
1.44mb
ReplyDeleteIf you want some harder questions, I could probably supply a few. :)
