instead of real-time helical scanning, the videotape could be duplicated linearly at high speed).
The closest to "magnetic printing" I'm aware of was the process Sony developed to duplicate Betamax tapes (i.e. Do you want to format it now -or- STOP: The disk media is not recognized, it may not be formatted. or- Disk is not formatted The disk in drive A is not formatted. Hence the floppy media can physically wear out. When you access a floppy disk, you may receive one of the following error messages: A:\ is not accessible. Unlike hard drives which have "flying heads", the read/write heads on floppy drives actually touches the media during normal operation. The tracks on 8", 5.25" and 3.5" floppies are all written magnetically by polarizing ferrite particles. However I recall from the old days that floppies had tracks “printed” on them and a magnet could mess that up, preventing them from being used. The issue is then a lack of ferrite material to polarize and generate current in the read head. worn out tracks) then erasure won't help. Maybe, if the damage is due to magnetic corruption.īut rather than use a magnet, a "bulk eraser" (an electromagnet that emits a strong alternating magnetic field) should be used.īut if the floppy has actual surface damage (e.g.
