Abstract: Technologies are provided for partially updating shingled magnetic recording (SMR) zones in SMR storage devices. An SMR storage device can receive and process a command to update a write pointer for an SMR zone to point to an arbitrary write position within the SMR zone. A partial SMR zone update command can be received and processed to modify part of the data stored in the SMR zone. A write position within the SMR zone where data to be modified is stored can be identified. Data stored in the SMR zone following the identified write position can be read to a temporary location and modified. A write pointer for the SMR zone can be updated to point to the identified write position. The modified data can then be written to the SMR zone, starting at the write position identified by the write pointer, or to another SMR zone of the storage device.

Abstract: The present technology relates to an information processing device and method, a recording medium, and a program, which can improve a data transfer speed. In the recording medium, a recording area is divided into a plurality of simulated zones and a set of the plurality of simulated zones composes a simulated zone group. Then, an address is set to each area in the simulated zones so that the addresses are interleaved between the simulated zones composing the simulated zone group. By interleaving the addresses between the simulated zones in this manner, a local seek operation or a rotational delay can be reduced and the data transfer speed can be improved when recording or reproducing data to the recording medium in more than one channel at the same time. The present technology can be applied to an optical disk.

Abstract: Various zone forwarding management techniques disclosed herein generally provide efficient methods of data caching, steering, mapping, and migration to reduce write amplification and command latency. In one implementation, a zone-forward storage medium management method includes receiving commands to write data sets to target LBAs included in a consecutive sequence of LBAs, selectively mapping the sequence of LBAs to a plurality of contiguous physical zones, and selectively writing the data sets to the physical zones. Various techniques may be used to migrate valid data of the plurality of physical zones to one physical zone.

Abstract: A data storage space configuration of a hard disk drive comprises a plurality of zones in which each one of the plurality of zones stores customer data. The data storage space configuration further comprises a plurality of database metadata storage spaces allocated in the plurality of zones, wherein the number of database metadata storage spaces is less than or equal to the number of zones. The database metadata may comprise temporary metadata. The database metadata may comprise write-ahead log (WAL) metadata. The database metadata may comprise staged-write (DEPOT) metadata for the purpose of interrupted write recovery.

Abstract: In one example, the disclosure is directed to a method comprising receiving, by a controller of a hard disk drive, a request to write a data block to a data storage platter of the hard disk drive. The data storage platter of the hard disk drive includes at least one random access zone and at least one sequential access zone. The controller determines a hinting value for the data block based on hinting information of the data block. The controller further determines, based at least in part on the hinting value, a location of the data storage platter of the hard disk at which to write the data block. The location includes one of the at least one random access zone or one of the at least one sequential access zone. The controller writes the data block at the location.

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.
