<p>A method and apparatus for magnet-optical recording are provided that can reduce heat in pulse driving of a magnetic head coil of a magnet-optical recording apparatus. Data inversion detection means 41-44 generate a signal TRDET that becomes the high level when a magnetic inversion of data occurs and becomes the low level when no magnetic inversion of data occurs. Means for reducing an exciting energy 45-47 use this signal TRDET so as to generate a strobe signal STRB that has a short period of the high level when a magnetic inversion of data occurs and a normal period of the high level when no magnetic inversion of data occurs. The magnetic head coil is excited during a period in which the strobe signal STRB is the high level, so that the pulsed magnetic field is generated, which is applied to a magnet-optical recording medium. <IMAGE></p> |
