USAGE OF STATE INFORMATION FROM STATE-SPACE BASED TRACK-FOLLOW CONTROLLER

摘要

A method according to one embodiment includes generating track following controller state information based on a positional signal of a head relative to a medium. One or more portions of the state information corresponding to particular frequencies are used to determine at least one of: lateral tape movement, tape skew, vibration operation conditions, and roller performance.

1. A method, comprising:
generating track following controller state information based on a positional signal of a head relative to a medium; using one or more portions of the state information corresponding to particular frequencies to determine at least one of:
lateral tape movement, wherein the lateral tape movement is used to position a coarse actuator to about a center position between outer extents of the lateral tape movement in response to determining the lateral tape movement,tape skew,vibration operation conditions, androller performance.
