DIATONE M-T05

Description
 
It is the cassette deck which inherited M-T01 type development thought and was developed.

The reliability of the mechanism is improved by adopting 2 motor systems.
direct-current motor for exclusive use in which a right inversion is possible is adopted as fast forward / rewinding for the FG servo direct-current motor as an exclusive motor which drives only a capstan.

The special oilless metal which overly gave precision finishing is adopted as a capstan and a capstan bearing after sintering. It is possible to make the coarseness of a bore side and roundness by this specular surface finishing of a micron order, without causing eye crushing.

Operation of a mechanism is controlled electronically, and any operation can fly a stop button even from Ord, and it can shift from it to the next operation at a stretch.

ASPS is carried and the unrecorded part of about 3 seconds can be automatically made during recording.

Bias and an equalizer can switch three steps independently.

The Dolbey circuit is carried.

The full auto stop adoption s Is, and if any mode of a Recording play and rewinding of operation finishes rolling a tape, a mechanism will be in a halt condition automatically.

By using an optional audio timer together, absence recording and an alarm clock play are possible.
