Abstract

A recording apparatus for an optical recording medium having a pregroove and address data includes a recording head apparatus and a controller. The recording head apparatus has an optical head device and records data on the optical recording medium along the pregroove. The optical head device radiates a light beam having an intensity which is enough to record the data on the optical recording medium. The optical head device includes a detector. The controller controls the recording head apparatus and receives an output signal supplied from the detector. The optical head device is controlled to move a recording start point from the previous recording start point by a predetermined value when the controller detects the occurrence of a recording error according to the output signal from the detector and restart recording the data from the moved recording start point on the optical recording medium.
