Abstract: | Various contact recording technologies for hard disk drives are reviewed. The advantages and disadvantages of each approach
to contact recording are analyzed. Experimental detection methods and simulation models for the contact force are introduced.
Some important technologies related to contact recording are addressed. The effects of lubricant and the short range forces
on contact recording are discussed, and the dynamic flying characteristics of a slider with spherical pad at trailing edge
are studied. It is suggested that a thermal protrusion slider with a spherical pad at the trailing edge may be a possible
approach for the success of contact recording. |
