摘要： A disk storage device stores write data in a cache area of a data buffer according to a write command from a host, reports write completion to the host, and then writes the write data in the cache area to a storage medium. The disk storage device stores the write data stored in the data buffer in a save area created on the storage disk in response to the reception of a command which requires integrity, other than a write command, and reports a response to the host. Therefore processing time of this command and response time to the host can be decreased, while maintaining the safety of the write data.
摘要翻译：磁盘存储装置根据来自主机的写入命令将写入数据存储在数据缓存器的高速缓存区域中，向主机报告写入完成，然后将写入数据写入高速缓存区域到存储介质。磁盘存储装置将存储在数据缓冲器中的写入数据存储在存储盘上创建的存储区域中，以响应于除了写入命令之外的需要完整性的命令的接收，并且向主机报告响应。因此，可以在保持写入数据的安全性的同时减少该命令的处理时间和对主机的响应时间。

摘要： According to one embodiment, a recording medium controller includes a recording medium, an input module, a reading module, and a writing module. The recording medium includes a write area and an escape area. The write area includes track groups. Each of the track groups is a unit for writing data and includes tracks. The input module receives a write command for data. The reading module reads data stored in the escape area and data from a first track group of the track groups. The writing module writes data received for the write command to the escape area, and writes merged data obtained by merging the data read from the escape area and the data read from the first track group to each track of a second track group of the track groups by using a shingle recording technique in which adjacent tracks are partly overlapped with each other.
