В) Demagnetizing
Residual magnetism, which degrades performance and can
patialy erase valuable tapes, gradually builds up in the
metal peris of the head assembly, etc. This pheromera
is due ю the топо magnete fid gonorated by tho
recordiplayback head and is en unavodable fact of tape
recording
То де! rid of this residual magnetism, demagnetize the head
area, capstan and quides after about every 8 hours of use
with e demagnetizer such as the Fostex Model HD-10, care-
fully following its operation instructions. (1 not camed out
рторепу, demagnetization can do more harm than good
Маке ABSOLUTELY sure that те R8 is tumed OFF when
demagnetizing, and tat no tapes are within 2 feet (06
meters). Do not turn on or even plug in a demagnetizer un-
less it is at least three fest (1 meter} away fiom the tace
recorder Approach the head area сому with the demag-
neizer turned on, and also remove it again slowly before
tuming t off at a distance of at least 3 feet
