Recording medium and recording device |
摘要 |
A recording disk has a surface provided with guide grooves for controlling the position of a recording head, and recording bits formed in the guide grooves for high-density recording. The recording bits have the shape of a tadpole in a plane. The width Ws of the recording bits is greater than the width Wg of the guide grooves. An AFM probe serving as a recording head travels along the guide grooves without running off the guide grooves. When a tip part of the AFM probe coincides with the recording bit, the tip part drops deep into the guide groove, whereby the recording bit is detected.
