Head demagnetization
In order to maintain good sound quality during recording and
playback, it is recommended that the head assembly be
demagnetized if distortion or poor sound quality persists after
cleaning the heads.
If the head assembly becomes magnetized, it could create noise
in the recordings, loss of high-frequency response or erasure of
valuable recordings.
Several types of head demagnetizers are available and may be
purchased separately at local electronics supply stores.
Follow the instructions that are supplied with the device.
Do not bring any type of metal objects or tools such as magnetic
screwdrivers in contact with the head assembly.
