ABSTRACT:
A data reproducing apparatus for reproducing data recorded on multi-tracks, comprises a signal transducer for simultaneously reproducing pre-recorded frame signals from a plurality of tracks on a recording medium, a write-in address generating circuit provided in each of transmission systems for reproduced signals from the tracks obtained in parallel from the signal transducer, for generating a write-in address indicating the number of bits of data within one frame signal from a counter which counts clock pulses having a period equal to the transmission bit rate, a memory into which data within frame signals reproduced from the tracks are written and then read out, and a memory control circuit for controlling the memory so as to successively and recursively apply the data within the frame signals reproduced from the tracks and write in the data at the write-in addresses obtained from the write-in address generating circuit, and read out the written-in data from the memory with the timing arranged after a predetermined time has elapsed.
