Magneto-optical recording and reading-out method. |
摘要 |
<p>The disclosure describes a magneto-optical recording and readout method which comprises making a tape-type magneto-optical recording medium (1) run in front of at least a single pole of a permanent magnet (2) or an electromagnet at a position forwards of an optical head relative to the running direction of said recording medium, without contacting said magnet so as to cross at a substantial right angle to magnetic force lines (3), thereby initialising said recording medium or erasing information therein, said tape-type magneto-optical recording medium (1) having at least a magneto-optical recording layer on one side of a base film having a thickness of not more than 50 mu m; and effecting recording of information by irradiating beams to the recording medium under application of an external magnetic field of not more than 24 kA/m. <IMAGE></p> |
