Abstract:
The disclosed technology provides a method that improves SMR throughput in vibration in storage systems. In one implementation, the method comprises receiving a write command to write data on a first track in a band of a storage medium, performing a vibration detection scheme to identify vibration events, determining if a number of vibration events is above a predetermined threshold, skipping the first track responsive to determining the number of vibration events is above a predetermined threshold, seeking to a second track adjacent to the first track, increasing an OCLIM on the second track adjacent to the first track from a default OCLIM to an increased OCLIM, and shifting the writer center on the second track adjacent to the first track.
