摘要： A disk subsystem provided with a cache has a capability of executing writing of data of discontinuous dirty blocks on a cache memory into a disk and reading of data of discontinuous empty blocks on the cache memory through the effect of just one DMA transfer. When the dirty data discontinuously ranged on a cache segment is written on the disk, the microprocessor provides a bit-map to a harddisk controller (HDC) as control information for data transfer. If an i-th bit of the bit-map is "1", the HDC operates to write the i-th block data sent from a direct memory access controller (DMAC) onto the corresponding sector of the disk. If the i-th bit is "0", the microprocessor serves to stop the write of the data and control a read/write head to wait until it passes the corresponding sector.
摘要翻译：设置有高速缓存的磁盘子系统具有执行将高速缓冲存储器上的不连续脏块的数据写入到磁盘中并且通过仅仅一个DMA传输的效果来读取高速缓冲存储器上的不连续空块的数据的能力。当在缓存段上不连续地限制脏数据被写入磁盘时，微处理器提供位图到硬盘控制器（HDC）作为数据传输的控制信息。如果位图的第i位为“1”，则HDC操作以将从直接存储器访问控制器（DMAC）发送的第i个块数据写入到磁盘的相应扇区上。如果第i个位为“0”，则微处理器用于停止写入数据并控制读/写头等待直到相应扇区通过。

摘要： A cache control method and a rotary storage device are capable at a low cost, of improving the hit rate and minimizing the processing time in the event of a miss hit. The rotary storage devices includes a plurality of disk units, an upper-level interface circuit, a cache controller, a cache memory, and a control processor. In each disk unit, the storage area of each disk is subdivided into an ordinary user data area and a secondary cache data storage area including a group of consecutive cylinders. Data which has overflowed from the cache memory is sequentially written in the secondary cache data storage area so as to be later transferred therefrom to areas of the user data area according to addresses inherent thereto when traffic of upper-level input/output processing is relatively low. In the case of a miss hit of the cache memory during a data read operation, access operations are performed first to the secondary cache data storage area and then to the user data area.

摘要： A method of forming servo information in a magnetic disk apparatus of a sector servo system. Servo information is recorded in advance at the beginning of each of the sectors, and includes a DC erase signal, a track address signal and a burst signal. The track address signal indicates on which track of the magnetic disk the sector is located, and is formed by expressing the track address in Gray code and interleaving a dummy code into the Gray code. Servo information is recorded using an NRZI system or an RLL coding method. Servo information in which the dummy code is interleaved is decoded after the dummy code is removed at the time of demodulation.
