IS UNCOVERED).
In the event of a Read error, up to 10 attempts should be made to recover with re-
reads. If after 10 attempts the data has not been recovered, step the head several tracks
away and then re-position to recover the data. Unloading the head when data transfers
are not imminent will increase the data reliability and extend the diskette life.
2.4 DISKETTE HANDLING RECOMMENDATIONS
Since the recorded diskette contains vital information, reasonable care should be
exercised in its handling. Longer diskette life and trouble free operation will result
if the following recommendations are followed.
a. Do not use a writing device which deposits flakes e. g., lead or grease pencils,
when writing on diskette jacket label.
b. Do not.fasten paper clips to diskette jacket edges.
c. Do not touch diskette surface exposed by jacket slot.
d. Do not clean diskette in any manner.
e. Keep diskette away from magnetic fields and from ferromagnetic materials that
may be magnetized.
