In addition to the race to the bottom declining quality, the reliability
may also have been slightly affected by
change in linear density (physical length of track),
48tpi V 135tpi,
reduced write current (with 300 Oersted V 600 V 750)
Or maybe it's the need for fingerprint oils on the media! 3.5" keeps
fingers away more than 5.25 or 8". On the Lisa "Twiggy" diskettes, they
made special provision to get more thumb prints.
If it were only still in the public consciousness, I can imagine CSI
dialog, "They cleaned up the crime scene, but I know one place where we
can get a thumbprint of the computer operator!"
