Abstract

Lubrication of flexible magnetic recording media is necessary to reduce wear of the media and the recording head. Furthermore, the friction between the head and the media should be low to prevent sticking. In order for a liquid lubricant to be effective, it should migrate to the head-media interface where it is required, and it should continue to migrate throughout the lifetime of the media. A liquid lubricant of glycerol tri-oleate or glycerol di-oleate has been found to reduce the friction of magnetic media and to be stable with time.
