Abstract: Methods and systems that reduce off-track write retry operations in shingled magnetic recording systems. In one implementation, the method includes writing data to an initial track, determining which side of the initial track is a shingled side, calculating a percentage of position error signal (PES) at a shingled side end of the initial track (PES1) when an off-track write operation occurs, determining whether the PES1 meets a first pre-determined threshold, continue writing data to a second track responsive to determining the PES1 is below a first pre-determined threshold, calculating a percentage of PES at a shingled side end of the second track (PES2), determining whether a combined value of PES1 and PES2 is above a second predetermined threshold to determine a probability value of the initial track being erased, and continue writing to a third track if the combined value is below the second predetermined threshold.

Abstract: The disclosed technology provides a method that reduces time to recover in storage systems. In one implementation, the method comprises entering an idle status, determining if there is an incomplete band update operation, invalidating a media scratch pad (MSP) by clearing headers responsive to determining there is no incomplete band update operation, performing a power cycle, reading an MSP header, and determining if an MSP header is valid. If a rude power cycle occurs and the MSP header is determined to be valid, an MSP is examined, and restored if required. If a safe power cycle occurs, an MSP restore operation is not required, reducing time to recover.

Abstract: A method includes moving data in a defect range from a defective area of a data storage medium to a reserve area of the data storage medium, and identifying the defect range by an address of a start of the defect range and a defect length.

Abstract: A data storage device includes a data storage medium and a controller. The controller performs a boot-up sequence that includes operations that transition the data storage device from a lower operational state to a higher operational state in which the data storage device is ready to service host commands. The controller also carries out metadata updating operations independently of the boot-up sequence operations. Carrying out the metadata updating operations independently of the boot up sequence operations prevents the metadata updating operations from substantially contributing to a boot-up time.
