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.

The hysteresis 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.
