Data sector/servo split generator for a disk drive |
摘要 |
A data sector/servo split generator is disclosed for a disk drive apparatus implementing a zone bit recording format and having an embedded sector servo system where servo sector fields split at least one data field on a surface of a disk in the disk drive apparatus. A first counter is provided to count an amount of time to the beginning of a data field, and a first signal (SECTOR) is generated to indicate when the beginning of a data field is encountered by a read/write head in the disk drive. A second signal (SPLIT-VALID) is generated by the data sector/servo split generator if a next data field after the generation of the SECTOR signal is split by a servo sector field. A second counter counts a predetermined number of data bytes transferred between a surface of a disk in said disk drive apparatus and said disk controller, so that a third signal (SPLIT) is generated, the SPLIT-VALID signal is generated, when a servo sector is encountered in a data field by the read/write head. The SECTOR and SPLIT signals are supplied to a disk controller which uses those signals to control the transfer of data to and from the disk.
