Abstract
A data storage device can include a recording medium; a controller unit to generate control signals in response to write information and write commands; and a transducer section coupled to receive the controls signals, and in response, write the write information into the recording medium and form a data protection pattern in the recording medium adjacent to the write information.
Claims10
A data storage device, comprising:
- a recording medium;
- a controller unit to generate control signals in response to write information and write commands;
- and
- a transducer section coupled to receive the controls signals, and in response, write the write information into the recording medium and form a data protection pattern in the recording medium adjacent to the write information;
- wherein
- the data protection pattern is formed in an area of the recording medium managed by the data storage device to not store write information thereon, and
- the controller unit is configured to determine if the write information has a predetermined classification, and to generate the control signals in response to the write information having the predetermined classification, and to not generate the control signals in response to the write information lacking the predetermined classification.

A system, comprising:
- a recording medium;
- and
- a controller unit configured to control a recording of write information in the recording medium and a form at least a first data protection pattern in the recording medium adjacent to the write information that improves data storage characteristics of the write information as recorded in the recording medium;
- wherein
- the data protection pattern is formed in an area of the recording medium managed by the system to not store write information thereon, and
- the controller is configured to form the first data protection pattern when the write information has a predetermined classification, and not form the first data protection pattern when the write information does not have the predetermined classification.
