Abstract

A long standing problem of wear in both the magnetic recording head and tape plagues the magnetic recording industry because wear severely limits the life of these systems. Additional wear problems arise when magnetic tape is used as a transfer medium for toner developed magnetic latent images. In this case, the recording heads suffer not only the frictional sliding contact of the magnetic tape, but also abrasion from residual toner particles that are not removed by the tape cleaning system. Since thin-film magnetic recording heads are composed of dissimilar materials, the wear problem is particularly severe at the various interfaces between different materials.
