Method for recording information on optical recording medium and optical recording medium on which information is recorded |
摘要 |
An information recording device that records information on an optical recording medium includes: a laser beam generation device for generating a pulse light with a pulse width less than 1 ns; and a mark formation device for collecting the pulse light and irradiating a recording layer in the optical recording medium with the pulse light so as to form a mark in the recording layer, whereby generation of re-crystallization regions and a variation in the position of marks can be controlled appropriately and information can be recorded on an optical recording medium at high density.
