GENERAL INFORMATION
NOTE
AU of HP's computers spare 4 complete tracks on the flexible
disc. This reduces the usable storage space to 512*9* 154
(bytes/sector times sector/track times unspared tracks). This
total equals 709.632 Kbytes for the 3 1/2-inch floppy disc
drive.
NOTE
The flexible disc in the HP 913 3D Disc Memory is designed
for operation in a typical office environment. Use of the
equipment in an environment containing dirt, dust, or cor-
rosive substances will cause the flexible disc drive and
medium life to be drastically reduced.
Equipment Supplied
The following equipment is supplied with each HP 9133/34D disc memory.
