| 摘要 |
<p>This invention relates to a photomagnetic recording method for writing data into a photomagnetic medium by using a magnetic head whose magnetic field is modulated by a recording signal and an optical pickup. In accordance with the present invention, a first data pit group is first recorded on the photomagnetic recording medium with gaps greater than a predetermined data pit recording gap and then each data pit of a second data pit group is recorded between the adjacent data pits of the first data pit group. A photomagnetic recording apparatus according to the present invention can cope, by interleaving write method, with both the factors of frequency characteristics of the magnetic head and the thermal interference of adjacent pits that limit high density recording or high speed access, and can accomplish both high density recording and high speed access.</p> |
