Abstract

PURPOSE: To make the selective recording, etc., of analogue and digital signals possible well by switching a recording and reproducing circuit, the tape speed, etc., according to analogue signals or digital signals.

CONSTITUTION: When command A/D 10 becomes high-level, the write of analogue signals such as voice is instructed, and rotation direction command 9 of motor 4 and command R/W 11 become high-level. Then, the motor started by the high level of command 8 rotates in a high speed in a prescribed direction, and the tape runs in a high speed, and simultaneously, the voice code is recorded on the magnetic tape from A/D code generator 17 through write circuit 25, write/read switching part 24 and head 3. The read of this recording data is performed similarly, and the write and read of digital data is performed similarly through the command A/D, etc., in a tape running speed which is the half of the tape running speed at an analogue signal processing time, so that the recording and the reproducing of analogue signals and digital signals can be performed with a good S/N. However, the gap width of the reproducing dual head is selected to be approximately 1.5 and 5μ for analogue signals and digital signals.
