Method and apparatus for recording with a magneto-optical recording medium applying one period of an alternating magnetic field to a unit domain length |
摘要 |
A magneto-optical recording medium includes a recording layer and a reproducing layer respectively formed by magnetic layers on a substrate. A record magnetic domain is formed within the recording layer by using a magnetic head, which is transferred into a reproducing layer by irradiating a laser beam upon reproduction. The physical length in recording a unit bit is taken as a unit domain length. Where the unit domain length is 1T and "1" is recorded in 1T, "1" is recorded in a former half 1T/2 and "0" is in a latter half 1T/2 by applying one period of an alternating magnetic field to the unit domain length.
