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:
vibration operation conditions of a drive environment, wherein the one or more portions of the state information used for determining the vibration operation conditions correspond to one or more lower frequency portions of the state information relative to those portions of the state information usable for determining roller performance and higher than those portions of the state information usable for at least one of lateral tape movement and tape skew; androller performance, wherein the one or more portions of the state information used for determining the roller performance correspond to one or more higher frequency portions of the state information relative to those portions of the state information usable for determining at least one of the vibration operation conditions, the lateral tape movement, and the tape skew.
