It is 4 truck stereo tape deck which investigated reliability and stability.
While raising the wow and flutter engine
performance by adopting a belt drive system, 2 speed systems by belt change are
taken. This change is designed also perform the change of the equalizer
characteristic of amplifier simultaneously with speed.
synchronous motor is used for a motor and it has prevented tape speed changing
by changing the voltage of a power source with smooth rotation operation.
Equalizer amplifier and an output amplifier part adopted the low-noise
transistor as the input side, and have improved SN while they apply a lot of
feedbacks to the amplifier of a direct connection system, respectively and
measure distorted reduction.
0.1mm of 2-micron gap permalloy lamination
head designed specially is adopted as a head.
If a tape finishes
winding, the auto stopper which detects that the tape was lost and turns off a
motor automatically sticks, and it has prevented a tape hurting.
