Abstract
The relationship between the fluidity and adsorption force of lubricant on thin film magnetic rigid disks has been investigated. The adsorption force of lubricants to carbon surfaces increases with an increase in relative dielectric constant of benzene derivative end groups. Disks coated with perfluoropolyether having high adsorption forces show high CSS (contact start/stop) durability. It is found that lubricant layers can be divided into fluid and adsorption parts. The ratios of the fluid to the adsorption parts in the coating affect mechanical durability
