Abstract
A high speed magnetic disk recording system is described in which the recording medium comprises a substrate having a magnetic coating thereon, and a magnetic recording transducer is operated in physical contact with the recording medium. The magnetic transducer comprises a single crystal material on at least the surface which contacts the recording medium. The single crystal material has a high thermal conductivity, a low friction coefficient and a high surface energy so that, when relative motion is provided between the magnetic recording transucer and the recording medium, an attractive force is generated which maintains the magnetic recording transducer in contact with the recording medium so that high density recorded data can be reliably written and sensed without excessive wear to either the magnetic transducer or the recording medium.
