Abstract:
An apparatus for data reproducing in a disk storage system, the apparatus comprising:a disk having a plurality of data sectors as recording areas of data access units arrayed in a circumferential direction, and a data split in which a data sector next to adjacent data sectors is separated by a servo area with servo data recorded therein;a head for outputting a read signal read from the disk by the data sector unit;means for generating a servo gate as an enable signal used when the servo data is read by the head and for controlling positioning the head;data reproducing means for executing reproduction processing of data recorded in the disk from a read signal output from the head;sector signal generating means for generating a sector signal for detecting a lead portion of the data sector;first read gate means for generating a reference read gate signal for determining a timing of starting reproduction processing of the data reproducing means; andsecond read gate means for generating a restart read gate signal when recorded data are continuously reproduced from previous and next adjacent data sectors while the data reproducing means is reproducing the data stored in one of the data sectors, the second read gate means generating the restart read gate signal for determining a timing of starting reproducing of the data stored in the next data sector, after the sector signal generating means generates the sector signal corresponding to the next data sector and before the first read gate means generates the reference read gate signal corresponding to the next data sector, the second read gate means switching the restart read gate signal ON before the reference read gate signal corresponding to a next data sector when recorded data are continuously reproduced from adjacent data, sectors, and when the next data sector is separated by the servo area, switching the restart read gate signal OFF in synchronization with the servo gate and switching the restart read gate signal ON again in synchronization with the reference read gate signal.
