Data recording device and data recording control device

摘要

A data recording device for recording data on an optical disc by irradiating a laser pulse on the optical disc while controlling rotation of the optical disc at a constant angular velocity. The device includes a laser condition varying unit (31, 40, 51, 60, 70, 80) that changes a peak value of the laser pulse in accordance with a value relating to a linear velocity of the optical disc at a position at which the laser pulse is irradiated.
