Abstract: A digital audio tape recorder having a function of reproducing the magnetic tape with digital data recorded thereon in the state of high-speed travelling by a plurality of rotary heads for the purpose of high-speed search and cue/review. In high-speed search, the parity of the read digital data is checked to select the digital data identified by the greatest majority. The data are selected after discriminating the data supplied from the sub code area 1 from the data supplied from the sub code area 2 in REW search but without such discrimination in FF search. In cue/review, the number of identified parities is counted for each of the plurality of rotary heads. The digital data read out by the magnetic head which has supplied the digital data having a smaller number of identified parities is prevented from reproduction. The digital data read out by the magnetic head which has supplied the digital data having a larger number of identified parities is interpolated and reproduced.

Abstract: The structure of the RAM in the signal processing circuit of a digital audio tape recorder. When the reproduction mode is switched over to the recording mode, or the sampling frequency for the recording is changed to a different sampling frequency, a RAM clear signal is automatically output. At the output of the RAM clear signal, a converting circuit disposed in the route from a read address generator to an address bus is operated so as to read the digital sound data from the RAM and supply the digital sound data to a recording head and record it on a magnetic tape. Address signals only in the odd blocks of the RAM are generated and null data is serially written thereinto, thereby clearing the RAM.
