    Abstract: A storage system such as a hard disc drive (HDD), solid-state drive (SSD), hybrid drive (SSHD), storage rack, set of storage racks, JBOD, array of discs, etc. may include a variety of storage media. Failures may be detected in the storage media of the storage system. Such a failure may affect the physical capacity of the storage system. A storage controller of the storage system initiates a media conversion that converts a portion of the storage media from media storing data according to a first recording scheme to a media storing data according to a second recording scheme. The second recording scheme stores data at a higher density compared to the first recording scheme.

    Abstract: A method for managing data bands within an interlaced magnetic recording (IMR) architecture includes transmitting read/write characteristics of a logical block address space, the read/write characteristics including coupling information characterizing a physical arrangement of data blocks associated with different logical zones in the logical block address space, where each of the logical zones spans a continuous range of logical block addresses mapped to a series of data blocks physically interlaced with another series of data blocks corresponding to another one of the logical zones. The method further provides for executing a write command instructing a data write to a target logical zone of the logical zones, the write command being generated based on the transmitted coupling information.

    Abstract: Systems and methods are disclosed for isolated bands of fractional tracks in data storage devices, particularly devices employing shingled magnetic recording. In one embodiment, a device may comprise a data storage medium including a first data storage area including tracks overlapped in a shingled manner and having a first circumferential portion of a track to store data, a second data storage area, and a guard area disposed between the first data storage area and the second data storage area, the guard area including a second circumferential portion of the track as a partial guard track. In some embodiments, the guard area may include at least one sector in the first circumferential portion of the track, such that at least one sector of the guard area is interposed between data storage sectors of the first data storage area.

    Abstract: The disclosure is related to systems and methods of managing a memory. In a particular embodiment, a memory channel is disclosed that includes multiple memory units, with each memory unit comprising multiple garbage collection units. The memory channel also includes a controller that is communicatively coupled to the multiple memory units. The controller selects a memory unit of the multiple memory units for garbage collection based on a calculated number of memory units, of the multiple memory units, to garbage collect.
