摘要： Data are stored on magnetic tape along successive tracks extending obliquely across the tape, in each of several areas including a lead-in area, a data area and an end-of-data (EOD) area. Each track comprises successive blocks or fragments of data, and each fragment has a compact header containing a synchronization byte, six information bytes and two parity bytes. The information bytes include a fragment ID, an area ID sub code identifying the area in which the fragment is located, and various other sub codes relating to logical structure of the data. The inclusion of an area ID sub code and logical structure sub codes in the (compact) header of every fragment facilitates reliable searching of the data stored on the tape at high tape advance speeds.

摘要： A digital audio tape recorder is used as a digital data storage recorder and digital signals containing main data and sub-data are recorded in separate areas in each track of a plurality of tracks formed on a recording medium, wherein a predetermined number of tracks constitute a group and a plurality of groups are recorded on the medium. In the sub-area an identification signal is further recorded which indicates whether or not main data recorded in the main areas of a given group is same as the main data recorded in the main areas of preceding and subsequent adjacent groups. When identical data is multiply written for a plurality of units, a division of the multiply written portions is detected, and signal processing is facilitated.

摘要： The invention relates to a digital signal reproducing apparatus to which continuous blocks of input data are supplied, each block consisting of a PCM signal which was error correction coded and additional codes which were subjected to error detection or error correction coding processes. The error pointers are set independently of the result of the error correction of the PCM signal on the basis of the decoding state of the decoder for decoding the additional codes using the error detection code or error correction code.

摘要： A decoding apparatus in which the operation to write error correction coded data into a memory and a decoding processing operation of the data read out of the memory are executed in parallel. This decoding apparatus comprises: a comparator for comparing the address to write the data into the memory with the address in the memory for the decoding processing operation; and control means for inhibiting the writing operation when it is detected by the comparator that the decoding processing operation is precedent to the writing operation. With this apparatus, the data which was subjected to the correcting process is prevented from being rewritten into the memory and the pointer derived by the decoding process from being broken.
