Data Sector Configuration and Data Sector Timing Generator for High Capacity Hard Disk Drives

摘要

1. TECHNICAL FIELD OF THE INVENTION;The present invention relates to a hard disk drive, and more particularly, to a data sector configuration method and a data sector timing generator having a configuration in which an ID area is included in a data area.;2. Technical problem to be solved by the invention;The present invention provides a data sector configuration method for implementing a high capacity hard disk drive by including an ID area in a data area, and a data sector timing generator for generating a lead gate signal or a write gate signal in an enabled state for all the data sectors. .;3. Summary of Solution to Invention;A data synchronization area for providing synchronization for reading information recorded in a data sector, an ID address mark area for recording ID address marks of the data sector, a sector number area for recording sector information of the data sector, Split and flag areas in which split information and flag information for holding data processing up to a predetermined period are recorded when predetermined data are separated by servo sectors, PAD areas for separating ID areas and data areas, and the data sectors. Defect occurs in the data address mark area for indicating the validity status of data recorded in the data storage area, the data area in which data transmitted from an external device such as a host computer is recorded, and the data recorded in the data area. ECC area where error correction code is recorded for automatic error recovery is sequentially allocated It is characterized by configured.;4. Important uses of the invention;It can be used for data sector configuration and high data sector timing generator for high capacity hard disk drive implementation.
