Land/groove recording properties on a magnetically induced super-resolution (MSR) disk has been investigated. We prepared an exchange coupled type of MSR disk with double magnetic layers and examined the read/write characterisitics for various track pitches with magnetic field modulation recording. As the results, a track pitch of 0.65 μm was available for practical use from the point of view on crosstalk and crosswrite properties. We have also developed a new groove format in order to obtain address information on both lands and grooves.
