14. Playback Muting (Refer to Fig. 16)
During the solenoid initial-energization period,
playback muting is operated for click sound preven-
tion, but depending on the switching mode, the
muting time is changed. (Path @))
(According to time constant of R712 and C710—
712 on the solenoid initial-energization circuit.)
forward (»)——~ PAUSE (1) : about 0.4 seconds
STOP (@)———= forward (») : about 0.2 seconds
PAUSE (")——> forward (») : about 0.2 seconds
Muting time at the switching period from forward
mode to PAUSE mode is longer than other switching
period. This is to prevent noise caused by slight
movement of tape when tension arm moves at the
time just changed into PAUSE mode.
