Tape Drive Head Cleaning Procedure
The tape drive head (also called the tape head) should be cleaned at least once a
year. However, as part of the preventive maintenance strategy, it is
recommended that you inspect the tape head during each maintenance visit
and that you clean the tape head several times a year. In addition, a dated
label should be placed on the tape drive unit after the tape head is cleaned. You
should also complete the “AT&T Preventive Maintenance Log” sheet. (Refer to
Chapter 5, ‘‘Routine Maintenance Procedures’’
New tapes leave more abrasive particles on the tape head. Therefore, if a new
tape is used, issue the test tape long repeat 3 command, and then clean the
tape head.
The tape head can be accessed for cleaning from the front of the drive by opening
the tape access door with your finger. See
Table 10-605.
