Abstract

PURPOSE: To attain a double speed mode with use of a signal processing circuit having the same capacity as conventional by using the function of a half speed mode to obtain the double speed mode.
CONSTITUTION: A servo control circuit 11 controls a drum motor of a drum device 10 of a tape drive mechanism 9, a capstan motor of a capstan device 13, and a reel motor of a reel device 14 in response to the instructions given from a modulation circuit 7, a system microcomputer 12, etc., in order to secure a drum revolving speed and a tape speed which are double as high as those ensured in a half speed mode. The microcomputer 12 controls a system controller 5, a subcode generating circuit 6, a tape drive mechanism 9, and a servo control circuit 11 in each prescribed timing with key operations of a key/display part 15. At reproduction a tape which is recorded in a double speed recording mode is reproduced by a reproduction circuit with the same clock frequency, the same drum revolving speed, and the same tape speed as those of the half speed mode. Thus it is possible to record and reproduce the data in a double speed mode with use of a conventional signal processing circuit.
