Apple II disk formats

[Slor <semaj@rols.ten>]

This may be somewhat related to the thread on rescuing old diskettes, but 
probably not enough to clutter that one up. :)  Can anyone here give me the 
exact format layout for Apple II 3.5" and 5.25" disks?  As an example of 
what I'm looking for, take a portion of the standard fdprm file on many 
Linux systems:

#               size sec/t hds trk stre gap  rate spec1 fmt_gap
360/360          720     9   2  40    0 0x2A 0x02 0xDF     0x50
1200/1200       2400    15   2  80    0 0x1B 0x00 0xDF     0x54
360/720          720     9   2  40    1 0x2A 0x02 0xDF     0x50
720/720         1440     9   2  80    0 0x2A 0x02 0xDF     0x50
720/1440        1440     9   2  80    0 0x2A 0x02 0xDF     0x50
360/1200         720     9   2  40    1 0x23 0x01 0xDF     0x50
720/1200        1440     9   2  80    0 0x23 0x01 0xDF     0x50
1440/1440       2880    18   2  80    0 0x1B 0x00 0xCF     0x6C

It spells out the fine details of each common disk format and allows Linux 
to attempt guesses at what sort of disk you may be trying to read.  Can 
anyone provide corresponding specs (even if you only have part of the info) 
for Apple II formats?

thanks!
