摘要： A disk resident system for managing defective data sector information in a defective data sector map in a headerless format magnetic disk device. The defective data sector map is stored in gaps between fields in the headerless disk format itself or in existing disk administration fields. The defective data sector map includes a plurality of binary digits that individually correspond to a defective or non-defective status of an individual data sector on at least one section of at least one track proximate to the defective data sector map. The defective data sector map can be minimized by compressing repetitive 0's or 1's in the map. ECC coding and/or other redundancy checks can be included to ensure validity of the defective data sector map.

摘要： A method, apparatus, computer implemented method and computer programmed product for recovering data from a split sector associated with an inoperable servo timing mark. Instead of using a servo timing mark to synchronize the read/write head to the spin speed variation of a storage media, the trailing end of the data fragment preceding the inoperable servo timing mark is used as a reference point. After detecting the reference point, the read operation is halted a predetermined delay time after which the read operation is resumed recovering the data from the sector relying on the inoperable servo timing mark.

摘要： A method and apparatus for performing head switch operations in a magnetic disk system with a magnetic disk device that is segmented into a plurality of cylinders. The cylinders are grouped into an inner zone, a middle zone, and an outer zone. The inner zone is near the innermost area of the magnetic disk device. The outer zone is near the outermost area of the magnetic disk device. The middle zone is in between the inner zone and the outer zone. The head switch is performed from a current head at a current cylinder to a target head at a target cylinder. Prior to the head switch, the system determines if the current cylinder is in either the inner zone or the outer zone. If the current cylinder is in either the inner zone or the outer zone, then the system determines if the target cylinder is in either the inner zone or the outer zone. If the target cylinder is in either the inner zone or the outer zone, then the system seeks the current head to the middle zone and then performs the head switch. If the target cylinder is in the middle zone, then the system seeks the current head to the target cylinder and then performs the head switch. If the current cylinder is in the middle zone, then the system performs the head switch without seeking. After the head switch, the system seeks the target head to the target cylinder.

摘要： A method and apparatus for performing head switch operations in a magnetic disk system having a magnetic disk device that is segmented into a plurality of cylinders, which cylinders are grouped into an inner zone, a middle zone, and an outer zone. The inner zone is near the innermost area of the magnetic disk device. The outer zone is near the outermost area of the magnetic disk device. The middle zone is in between the inner zone and the outer zone. The head switch is performed from a current head to a target head. Prior to the head switch, the system determines if the current cylinder is in either the inner zone or the outer zone. When the current cylinder is in either the inner zone or the outer zone, the system seeks the current head to the middle zone, whereupon the system performs a head switch from the current head to the target head. When the current cylinder is not found to be in either the inner zone or the outer zone, i.e. when the current cylinder is in the middle zone, then the system performs the head switch from the current head to the target head without first performing a seek. After either of the above described head switch operations, the system seeks the target head to the target cylinder, when necessary.

摘要： a firm ware based technique related to managing defective data sector information in a disk drive. Specially, technique provides for a dynamic method by which the number of spare or served alternate sectors and their locations can be allocated in the event defective data sectors exist. One advantage of the present invention exists for certain applications where the capacity and/or configuration of the drive are configured at run time. The present invention also has the advantage of improving performance when accessing “grown” defects by allowing the block relocation information to be placed physically closer to the location of the defective blocks.

摘要： The invention comprises a magnetic disk storage system and comprises method for configuring the magnetic disk storage system. The magnetic disk storage system facilitates write and read operations that compensate for variances that are experienced with magnetic disk storage systems. When writing data to a data sector, the magnetic disk storage system utilizes a phase lock oscillator field that has a length that is specified for that data sector. When reading from a data sector, the magnetic disk storage system utilizes an incremental read delay that has a duration that is specified for that data sector. Data sectors with shorter data sector delay periods can have shorter phase lock oscillator fields than data sectors with larger data sector delay periods. This frees-up memory space and increases the capacity and performance of the magnetic disk storage system.

摘要： A method and system for laying out and accessing data in a disk drive system. The layout resides in a table in firmware of the disk drive system. The table includes multiple entries or rows, one corresponding to each different area in the disk media. The entry provides information about the range of block addresses in that area including the starting and end block address in the area, and information about the range of physical addresses including the head and the starting and ending cylinder number. A firmware routine finds the appropriate entry in the table and converts the block address to the physical address, or vice versa.

摘要： A method for maximizing buffer usage in a disk drive system. Control circuitry within the disk drive system tansfers the defective sector list for the disk to a buffer, and places the list in a reserved list area. The size of the defective sector list is then determined and the reserved list area is reduced to a size equal to the size of the defective sector list plus some spare room. If the newly sized reserved list area is not at one end of the buffer, it is then moved to one end of the buffer to leave the remainder of the buffer as a contiguous and expanded reserved user area for use data. The expanded reserved user area reduces the time of read or write operations in a disk drive.
