ABSTRACT:
In photomagnetic recording device and photomagnetic reproducing device where a record light beam is irradiated to a photomagnetic record medium in response to a record light thereby a pit is formed on the photomagnetic record medium, and a reproducing light beam is irradiated to the pit on the photomagnetic record medium thereby the record information is reproduced, since the record light beam is emitted intermittently in the light irradiation period that the pit is to be formed on the photomagnetic record medium among the record signal, the pit of nearly circular shape can be formed on the photomagnetic record medium, thus the information can be recorded on the photomagnetic record medium at high accuracy.
