Description
 
It is a stereo cassette deck corresponding to a metal tape.

The newly developed Sendust head is adopted as a Recording-play head, and correspondence to a metal tape is realized.
Moreover, the tape selector of four positions which added the metal position is carried.

ST mechanism (soft touch operation) is adopted as a tape control button, and soft operativity is realized.
This ST mechanism has the structure of operating head housing using the driving force of a motor, and does not require mechanical load for a play button. Moreover, the one-touch recording function which can be recorded only by pushing one recording button is carried.

The peak level indicator of 15 points is adopted as a level meter.

The Dolbey circuit which IC-ized the whole circuit is adopted. This is aiming at the improvement of the characteristic.
