[t]his means that you might get 30,000 bytes per >track on the inside and 90,000 on the outside -- but who cares? It's been done before. I don't think that it is quite done by changing the clocking rate, but I do know of disk drives that vary the number of sectors per track in order to fit the most data on the disk. I believe that the lowly Commodore 64's disk drive is one such device. >John Gilmore \scott -- Scott Hazen Mueller lll-crg!csustan!smdev City of Turlock work: (209) 668-5590 -or- 5628 901 South Walnut Avenue home: (209) 527-1203 Turlock, CA 95380
