Method of making magnetic recording medium utilizing die |
摘要 |
A non-magnetic substrate for a magnetic recording medium is formed or molded within a die. The die is designed to define embedment depressions on the surface of the resulting non-magnetic substrate. Any bumps or lugs formed on the inner surface of the die can be employed to form the embedment depressions on the non-magnetic substrate. A magnetic material fills the individual embedment depression so as to establish a magnetic block embedded into the surface of the non-magnetic substrate. The magnetic block can be utilized as a positional mark in a tracking servo control for a corresponding read/write head in a magnetic storage system.
