Memory disc, manufacturing method thereof, and method of manufacturing disc drive utilizing such memory disc |
摘要 |
A memory disc for use in a memory disc, comprising a lubricant layer which consists essentially of a non-fluid bonding lubricant, or comprises a lubricant layer which contains at least 90% of non-fluid bonding lubricant. Such memory disc is fabricated through steps of: forming a protective carbon layer; coating a lubricant on a disc substrate; subjecting the resultant substrate to an adhesion treatment to form a bonding layer of lubricant adhering to the disc substrate; and removing a free fluid layer of the lubricant remaining on the bonding layer. Thus, the memory disc has essentially no fluid component that can flow during read/write operations.
