Determining estimated position information of a magnetic recording tape using media thickness estimation

摘要

In one embodiment, a method includes acquiring actual position information from encoding on a magnetic medium, calculating estimated position information of the magnetic medium using a media thickness value, comparing the estimated position information with the position information acquired from encoding, determining whether an error between the estimated position information and the acquired position information is within a specified range, in response to determining that the error is within the specified range, storing the media thickness value to a memory, and in response to determining that the error is outside the specified range, changing the media thickness value. In another embodiment, an apparatus includes a controller and logic integrated with and/or executable by the controller, the logic being configured to cause the controller to perform the foregoing method.
