Abstract
In order to increase the performance and reliability of devices including rotatable storage media, individual characteristics of device elements or heads can be determined and used to set performance criteria. The off-track capability and track mis-registration of an element or head can be determined and used to set individualized end-of-seek criteria for elements or heads of devices including rotatable storage media.
Claims30
A device including a rotatable storage medium, comprising:
- an element capable of reading data from the rotatable storage medium, the element having an off-track capability and a track mis-registration;
- a controller adapted to enable a track-following operation when an end-of-seek criteria is met;
- and
- wherein the end-of-seek criteria is determined using the off-track capability and/or the track mis-registration of the element.
A device including a rotatable storage medium, comprising:
- means for determining an off-track capability and a track mis-registration of an element;
- means for determining an end-of-seek criteria using the off-track capability and/or the track mis-registration of the element;
- and
- means for enabling a track-following operation when the end-of-seek criteria is met.
A device including a rotatable storage medium, comprising:
- an element having an off-track capability and a track mis-registration;
- a controller adapted to enable a track-following operation when an end-of-seek criteria is met;
- and
- wherein the end-of-seek criteria is selected during a self-test of the device using the off-track capability and/or the track mis-registration.
A device including a rotatable storage medium, comprising:
- an element capable of at least one of reading data from and writing data to the rotatable storage medium, the element having an off-track capability and a track mis-registration;
- a controller adapted to enable at least one of a read operation and a write operation when an end-of-seek criteria is met;
- and
- wherein the end-of-seek criteria is determined using the off-track capability and/or the track mis-registration of the element.
