摘要： A buffer memory is prepared to temporarily store data sequentially read out from consecutive storage positions of a magnetic disk. When a read request is received from a host system, and an HDC reads out the requested data from the magnetic disk, the readout data is written in a buffer area in the buffer memory, which is assigned by a CPU and designated by a buffer management data portion, from the start position to the end position of the area. If the requested data exceeds the capacity of this area, the start address returns to a position indicated by a new start buffer address set in the buffer management data portion which is set by the CPU, e.g., a middle point in the buffer area, and the succeeding readout data is stored in the buffer area from the middle point to the end position. The requested data stored in the buffer memory is sequentially transferred to the host system. In the area extending from the start address, set in the buffer management data portion, to the end position, an area from which data is transferred to the host system is recognized as a free area, and succeeding data is sequentially stored therein by the HDC.

摘要： A CPU determines whether or not the disk access range designated by a read/write command from a host contains a defective sector. If the disk access range contains a defective sector, the CPU suspends disk access when a head has reached the defective sector. In this state, the CPU activates a buffer access circuit. The buffer access circuit copies data between an area of an alternate sector buffer and data buffer. The area of the alternate sector buffer stores data corresponding to the data written in the alternate sector allocated to the defective sector reached by the head.

摘要： According to one embodiment, a disk controller includes a receiver, a read-modify-write controller, and a wait controller. The receiver receives data in units of predetermined data length. The read-modify-write controller performs a read-modify-write operation when the receiver receives the data to write the data to a sector on a disk medium the rotation of which is controlled. The sector is longer than the predetermined data length. The wait controller delays the start of the read-modify-write operation by the read-modify-write controller for within the time which the disk medium takes to rotate once and which is substantially the same as the time required to control the read-modify-write operation.

摘要： In a disk storage apparatus which can concurrently process a plurality of data streams specified by a host, it is determined whether an error has occurred in a write operation specified by a write command being executed. If it is determined that an error has occurred, the write command is retried regardless of whether or not the time spent performing the write operation until the present time is within a time limit specified by the write command.
