摘要： Embodiments of the invention improve the cache hit ratio of read data. A hard disk drive (HDD) according to an embodiment of the present invention determines whether the read buffer should be used in its entirety or the partial continuous space should be used to read read-data from the magnetic disk. When the HDD determines use of the partial continuous space, the HDD specifies the sub-buffer which is a continuous space wherein the leading-end position and the trailing-end position are coupled to each other, and executes data writing to the sub-buffer in parallel with data reading from the sub-buffer and transmission thereof to the host. The sub-buffer capacity coincides with the data length of the back data.

摘要： Embodiments of the present invention provide a media drive capable of improving command processing performance by, when a plurality of commands is queued, shortening seek time and rotational latency, and also effectively making use of the shortened period of time. In one embodiment, a HDD includes a queue capable of storing a plurality of commands, and a queue manager for optimizing the execution order of the plurality of commands on the basis of whether or not the execution of each command requires access to a medium. The queue manager determines the execution order so that medium access processing of accessing a disk for execution, and data transfer processing of transferring data between the HDD and a host, are executed in parallel with each other. For example, read processing and transfer processing are executed in parallel with each other. The read processing is adaptive to read out a read command, data of which does not exist in the cache, from the disk into the cache. The transfer processing is adaptive to transfer a read command, data of which exists in the cache, to the host.

摘要： Embodiments of the invention raise the performance of a HDD by controlling the timing of notifying of command completion. In one embodiment, transmission of command completion notifications to a host is managed by a host interface manager. If two data write addresses respectively for two queued commands are adjacent or near to each other, that is, these addresses on the magnetic disk can be accessed without rotational latency, the host interface manager postpones the transmission of a command completion notification (X) concerning the first write command (X). Two command completion notifications (X) and (Y) are performed at a time after the write data (Y) for the next command is transmitted and its write to the medium is completed.

摘要： Embodiments of the invention reduce the host's wait time by controlling buffer for a data storage device. In a hard disk drive (HDD) disclosed herein, after write data from a host is stored in a write buffer, the size of a continuous free space left forward from the end position of the stored write data is detected. If the size is smaller than a criterion size, that is, the size is not large enough to store the next command's write data, the write buffer is searched for a continuous free space not smaller than the criterion size. If a continuous free space not smaller than the criterion size is detected, the HDD sets a write pointer to the continuous free space. This makes it possible to receive the next write data from the host and therefore reduce the host's wait time.

摘要： Embodiments in accordance with the present invention provide methods to record, in a rotating disk storage device, a data block in the unit of a logical sector on a recording medium on which a physical sector including a plurality of logical sectors is formatted. Extra addresses are acquired in a buffer to record write data blocks transferred from a host device. Data blocks are read from the recording medium in the unit of a physical sector. A skip read section discards data blocks having the same data blocks as the write data blocks by removing them from the read data blocks, and sends the remaining data blocks to the buffer. The buffer stores the data blocks in the order of recording in a physical sector.

摘要： Embodiments of the present invention provide a media drive that is intended for reduction in power consumption required for serial communications to/from a host, and a power saving method thereof. In one embodiment, a HDD includes: a cache; a host interface for transferring, to a host, transfer data read out from the cache; a host interface manager that controls the execution of commands so as to generate a transfer unnecessary period during which a command and transfer data need not be exchanged with the host; and a MPU that brings a serial communication part of the host interface into a power save mode during the transfer unnecessary period. The host interface manager determines the optimum data transfer timing of transferring data from the cache to the host on the basis of a transfer rate at which data is transferred to the host, and a read rate at which data is read out from a disk into the cache.
