Abstract: A method and system can be implemented to perform a read-modify-write operation on data recorded in a shingled media format. In one embodiment, a write operation on a band of data stored on a magnetic recording medium is initiated at an intermediate position within the band of data. This is particularly well-suited for data written by a shingled media write operation.

Abstract: Systems and methods for zone-based band mapping in a data storage device are disclosed. In one embodiment, a device may comprise a first data storage medium including a first band of tracks and a second band of tracks, each band of tracks including multiple adjacent tracks that are at least partially overlapped. The device may further comprise a processor configured to receive a write command to store received data to the first band of tracks, read previously stored data from the first band of tracks, modify the previously stored data with the received data to generate first modified data, write the first modified data to the second band of tracks, and assign a first data storage location indicator previously associated with the first band of tracks to the second band of tracks.

Abstract: In a shingled magnetic recording system, LBA can be dynamically allocated to an un-shingled media partition (UMP) based on a usage metric. In one implementation, the usage metric depends upon the frequency of writes to storage region and/or upon how recently the storage location has been written to. Data corresponding to one or more LBA ranges within a shingled data region may be rewritten to a storage region within a UMP on the disk.
Abstract translation: 在一个铺垫的磁记录系统中,可以根据使用度量动态地将LBA动态地分配给未绑定的媒体分区(UMP)。 在一个实现中,使用度量取决于对存储区域的写入频率和/或最近存储位置被写入的频率。 对应于带有加亮数据区域内的一个或多个LBA范围的数据可以重写到盘上的UMP内的存储区域。
