    • A magneto-optic recording medium in which a vertically magnetized film on which magnetized domains are recorded by applying a light beam and an outer magnetic field is provided along a recording track and structure bands which do not contribute to read out of the magnetized domains are provided on both sides of the recording track so that the magnetization state of the magnetized domains recorded on the vertically magnetized film is read from an area limited by the width of the recording track. By scanning the magneto-optic recording medium along the recording track with a light beam having a diameter larger than the width of the recording track so as to heat an area larger than the width of the recording track to a temperature exceeding the curie temperature of the vertically magnetized film and also by applying a magnetic field in a predetermined direction to the area irradiated with the light beam, the magnetized domains are recorded in accordance with the direction of the applied magnetic field, and the magnetization state of the magnetized domains is read out only from the area limited by the width of the recording track through the magneto-optic effect.
    • 提供了一种磁光记录介质,其中沿着记录轨道提供其上通过施加光束和外部磁场而记录有磁化畴的垂直磁化膜,并且提供了不有助于从磁化区读出的结构带 在记录轨迹的两侧上,记录在垂直磁化膜上的磁化畴的磁化状态从由记录轨道的宽度限制的区域读取。 通过使用直径大于记录轨道的宽度的光束沿着记录轨道扫描磁光记录介质,以便将大于记录轨道的宽度的区域加热至超过记录轨道的宽度的温度 垂直磁化膜,并且通过沿着预定方向施加磁场到照射到光束的区域,根据施加的磁场的方向记录磁化区域,并且读出磁化区域的磁化状态 只能从受到磁光效应的记录轨道的宽度限制的区域。
