![]() ![]() ![]() There were, in fact, attempts to create faster floppy drives.Ĭorporate Systems Center once sold a high-speed floppy drive called the X10 Accelerated Floppy Drive. ![]() If media is clamped with the motor on (as done in many existing floppy systems), mind the stress to the material if that is done at high speed!ĭesigning media so that it kept structurally sound even if punctured, driven against the read/write head by vibration/shock, suddenly braked in case something jams (observable with CD-ROM - high speed drives can rip damaged media to pieces!)Īlso mind that very early (8 inch era) drives did not use controllable BLDC motors but synchronous AC motors that might have posed some limitations (and made these limitations into specs). ![]() Probably also time needed to accelerate the medium to that speed without causing stress -> perceived speed, and/or cost due to much more complex electronics to read before medium is up to speed. The disc didn't always get perfectly centered by the loading mechanism, leading to rotational imbalance -> vibration, noise, wear More wear from media-to-sleeve friction - 5 1/4" and 8" discs typically touched the sleeve, which was lined with soft material -> wear, noise Dust in a hard drive can wreck it.) -> reliability Higher risk of drive/media damage if there is some imperfection in the media, or if any foreign matter gets into the drive or between media and sleeve (observable with hard drives. More complex data separator circuitry (due to higher bandwidth needed), probably better shielding on the r/w head wiring and drive-to-controller cabling -> cost, development effort Also, any significant rotational speed increase would have meant: As you mentioned, speed was considered sufficient for the typical applications at the time they were introduced. ![]()
