Patent ID: 7215628

Claim:
An optical information recording apparatus for recording information through the use of holography in an information recording layer of a recording medium, comprising: an optical head for irradiating the recording medium with information light and reference light such that information is recorded in the information recording layer in the form of interference patterns resulting from interference between the information light and the reference light; a recording medium moving device for moving the recording medium; and an irradiating position moving device for moving an irradiating position of the information light and the reference light such that the irradiating position of the information light and the reference light follows a predetermined position of the information recording layer for a predetermined period; wherein the irradiating position moving device moves the optical head such that the moving speed of the irradiating position is lower than the moving speed of the predetermined position before the irradiating position overlaps the predetermined position, and the moving speed of the irradiating position is adjusted to become equal to the moving speed of the predetermined position when the irradiating position overlaps the predetermined position.
