Optical information recording/reproducing device and associated method for increasing recording/reproducing speed
Abstract:
An optical information recording device includes: a section that acquires recording information that should be recorded on an optical information recording medium on which information are recorded by forming a recording mark at a position where an optical beam is focused on and from which the information are reproduced based on the reflectance of the recording mark; a section including at least one or more one-surface beam emission sections that emit a recording beam according to part of the recording information to one surface of the recording medium and focus the beam on a target position to form the recording mark; and an section including at least one or more other-surface beam emission sections that emit an recording beam according to the rest of the recording information to the other surface of the recording medium and focus the beam on a target position to form the recording mark.
