Apparatus and method for controlling tape moving speed of digital compact cassette recorder

摘要

The present invention relates to an apparatus and method for controlling a tape moving speed of a digital compact cassette recorder. In the past, when a digital signal is recorded on a tape, a capstan motor and a reel motor are supplied with a constant voltage irrespective of variation in tape amount and external disturbance The moving speed of the tape is influenced by such a fluctuation, so that it becomes faster or slower. Finally, there is a problem that playback can not be performed as the signal is recorded out of the phase synchronization range.;Therefore, in order to solve the conventional problems, the present invention is characterized in that a moving speed control of a tape during recording is performed by providing a pulse generator on a reel hub that winds up a tape and a reel hub that releases a tape, And the moving speed is controlled by making the sum of the detected periods constant, thereby eliminating the deviation in moving speed of the tape, and enabling errorless digital recording and reproduction.
