Cleaning the reel-to-reel magnetic tape drive
Follow these steps to clean the 9-track magnetic tape unit:
1. Remove the two plastic dust covers that protect the
magnetic head components by placing your fingers on the
edges of the covers and pulling them out from the face of
the tape deck.
2. Clean the magnetic head using a soft, lint-free cloth, lightly
moistened with the head cleaning solution. Wipe the
magnetic head working surface in the same direction that the
tape travels during data recording (forward).
CAUTION: Wiping in the wrong direction could scratch and
damage the head.
Also, wipe the areas around the magnetic head to remove
any dirt that the tapes may leave.
