Record and play heads
When the heads are used for a long period of time,
magnetic powder and dust accumulates on the tape-
contact surface of the heads. Thus causes imperfect
erasing or high frequency drop-off. Clean the heads with
a soit cloth soaked wish alcohol. ;
. Pinch roller and capstan
When the surfaces where the pinch roller and capstan
come into contact with the tape become dirty, the tape
speed becomes irregular and this causes wow and flut-
ter. Clean the tape-contact surfaces of pinch roller and
capstan with a soft cloth soaked with alcohol in the same
way as cleaning the heads.
* Do not wipe them with silicone grease nor oil and do
not use a strong solvent such as hexane or carbon
tetrachloride.
