Abstract

PURPOSE: To enable the recording and reproduction of digital data, by high and low speed feed of the same tape with a simple constitution, through the readout of data in each data block, based on the unit bit length reference signal in accordance with the tape speed.
CONSTITUTION: An input signal is converted into a binary digital signal at a PRE signal generating circuit 4. In this case, one of gate circuits 7, 8 is closed in accordance with high and low speed command signal and controlled with the clocks from low and high speed clock generating circuits 6, 5, to obtain the data different in the conversion bit width according to the tape specified speed, which is written in data area 30 such as high speed data block 3. On the other hand, to Pve, Post block areas 31, 32 at the beginning and end of the area 30, the reference signal according to high speed is written in, and this can also be applied to a low speed block 2. The bit width read-in clock at reproduction is selected and determined according to the read-in of the reference signal for blocks 31, 32, and recording and reproduction can be made by low and high speed feed of the same tape with simple constitution not requiring a tape speed detector.
