Follow these steps to clean and demagnetize your DATASSETTE™
STEP 1 Turn the computer off.
STEP 2 Press EJECT to open cover, then press PLAY to expose heads.
STEP 3 Put tape head cleaner on one side of a cotton swab. Gently wipe
the surfaces of RECORD/PLAY
and erase heads (see Fig. 1).
Scrub gently. Any build-up of tape oxide particles on or around the
head gap of the RECORD/PLAY
head may cause unreliable
performance.
Also clean pinch roller and other tape bearing surfaces if tape head
cleaner is suitable for this purpose (check label).
STEP 4 Plug in demagnetizer, and activate it while it is at least one foot
away from DATASSETTE™
heads.
STEP 5 Slowly move demagnetizer up to RECORD/PLAY head and around
on head surface. Rate of motion should be approximately one inch
per second during this time.
STEP 6 Slowly move demagnetizer to the erase head and then to all other
ferrous metal surfaces which come into proximity with the tape.
STEP 7 Now slowly move demagnetizer away from heads. Do not
,
deactivate field until demagnetizer is at least two feet away from
heads.
The tape head cleaning and demagnetizing procedure is now complete.
Inspect RECORD/PLAY surface for wear. If the tape has worn a groove on
head surface more than a couple of tape thicknesses deep, program reading
performance may be poor. If so, then replacement of tape head is indicated.
Normally, a few thousand hours of tape running time have been completed
before replacement is required.
