DIATONE M-T05
¥ 68,000 (around 1978)
Commentary
A cassette deck developed by inheriting the development philosophy of the M-T01 model.
The reliability of the mechanism is improved by adopting a 2-motor system.
A dedicated FG servo DC motor is used to drive only the capstan, and a dedicated DC motor capable of forward and reverse rotation is used for rapid feed and rewind.
The capstan and capstan bearings are made of oilless metal with a special ultra-precision finish after sintering. This makes it possible to obtain a mirror finish of micron order in both roughness and roundness inside diameter without causing clogging.
The operation of the mechanism is controlled electronically, and any operation can be shifted to the next operation at once by skipping the stop button from the electronic drive.
Equipped with ASPS, it can automatically create a non-recording part for about 3 seconds during recording.
The bias and equalizer can be independently switched to 3 levels.
Equipped with Dolby circuit.
The mechanism automatically stops when the tape is fully wound regardless of the operation mode of recording, playback or rewinding.
By using the separately sold audio timer together, it is possible to record your absence and play the alarm clock.
