Storage medium for storing data and servo information

摘要

A storage medium including a servo layer, a data recording layer, a heat sink layer, and a diamond-like carbon layer with a lubricant covering. The servo layer is configured to store servo information on the storage medium. The servo information is used to position a read/write head over the storage medium during a read/write operation performed by the read/write head on the storage medium. The data recording layer is configured to store data on the storage medium during the read/write operation performed by the read/write head on the storage medium. The heat sink layer is disposed between the servo layer and the data recording layer. The diamond-like carbon layer with the lubricant covering is disposed above the data recording layer.
