发明名称 A magnetic recording and reproducing apparatus.
摘要 <p>A magnetic recording and reproducing apparatus using a recording medium made of a ferrimagnet, comprises a magnetic head having a width larger than that of a track of the recording medium. For recording, light beams are radiated from a light source along one of the tracks to raise the temperature of the irradiated area to approximately a Curie temperature so as to allow recording only on that area. For reproduction, light beams are radiated from another light source onto areas on both sides of one of the tracks to raise the temperature of the irradiated areas to approximately a magnetic compensation temperature so as to allow reproduction only from the desired track, thus preventing crosstalk from the side tracks. &lt;IMAGE&gt;</p>
