Abstract
The disclosed technology provides a system and method that improves command completion time in a shingled magnetic recording device system. In one implementation, the system and method include receiving a write command to write data to a first track in a band in a recording medium, seeking to a first track, reducing an on-cylinder limit (OCLIM) from a default OCLIM to a reduced OCLIM by a predetermined amount on the first track, performing write operations on the first track with the reduced OCLIM, and determining if a transfer of data to the first track band in the write operations has been substantially completed. Upon determining that a transfer of data to the first track in the write operations has been substantially completed, the OCLIM is restored from a reduced OCLIM to a default OCLIM and write operations are performed on tracks adjacent to the first track.
