    摘要： An integrated data storage control system provides, in a single integrated circuit, RDC, servo logic, ATA interface, microprocessor, and other formerly discrete components in one highly integrated system design. The integrated circuit is rendered using a single integrated circuit technology type (e.g., digital CMOS) for all components. Analog and digital circuits are combined in such a way as to eliminate or reduce noise or interference in digital circuits from analog circuit components. Individual elements may have their outputs and inputs MUXed together such that individual elements can be selectively switched (during testing modes) such that the integrated circuit emulates or behaves in the same or similar manner as one of the prior art components. The present invention may be applied to magnetic hard disk drives (HDDs) or other types of storage devices such as floppy disk controllers, optical disk drives (e.g., CD-ROMs and the like), tape drives, and other data storage devices.

    摘要： A defect management system for use in a data storage system. The defect management system generates a track defect list comprising a sector defect record for each of a set of defective sectors in a track of a media surface. A sector defect record includes defect management information for each of the defective sectors. The defect management information may be generated according to one of several defect management schemes. The apparatus of the present invention stores the track defect list in a buffer or sector headers. The apparatus of the present invention maps a physical sector number to a logical sector number using the track defect list. If the track defect list is stored in sector headers, the present invention may use a ping-pong FIFO for processing the track defect list.

    摘要： A table driven method and apparatus for automatic split field processing in a disk drive system stores data representing the split fields after each servo mark of a frame. Each track of the disk drive system is divided up into frames or groups of sectors or equivalently servo marks, each frame comprising a predetermined number N of sectors and a predetermined number M of servo marks. Beginning from the INDEX mark, after every N sectors or equivalently M servo marks, the next sector must start after the next servo mark. The value N is a constant within each zone on a disk but can vary from zone to zone as the storage density changes. The information for each servo mark within a frame is stored in a frame table in the buffer memory. A starting address pointer and an ending address pointer are used to keep track of the starting and ending addresses, respectively, of the frame table. An address pointer is used to point to the current entry of interest in the frame table. For each servo mark within the frame, a sector pulse counter is stored, representing the number of sector pulses between the current servo mark and the next servo mark. A first time delay DY1, representing the delay from the current servo mark to the first sector pulse to be generated and a second delay value DYS, representing the size of the last split field before the next servo mark are also stored.

    摘要： A semiconductor mass storage device can be substituted for a rotating hard disk. The device avoid an erase cycle each time information stored in the mass storage is changed. Erase cycles are avoided by programming an altered data file into an empty mass storage block rather than over itself as a hard disk would. Periodically, the mass storage will need to be cleaned up. Secondly, a circuit and method are provided for evenly using all blocks in the mass storage. These advantages are achieved through the use of several flags, a map to correlate a logical address of a block to a physical address of that block and a count register for each block. In particular, flags are provided for defective blocks, used blocks, old versions of a block, a count to determine the number of times a block has been erased and written and an erase inhibit flag. Reading is performed by providing the logical block address to the memory storage. The system sequentially compares the stored logical block addresses until it finds a match. That data file is then coupled to the system.
