Patent ID: 7826316

Claim:
An optical disc drive for recording data on a recordable optical disc, the drive comprising: a spindle motor that rotates the optical disc; an optical pickup that irradiates the optical disc with laser light to conduct recording; a pickup controller that controls an irradiating position of the optical pickup; and a controller that controls the process of recording on the optical disc; wherein, while recording the data at a specified address on the optical disc, the recording controller judges whether the recording process has been executed to completion properly, and if the recording process is judged to have failed, the recording controller stops the process and activates the optical pickup to erase the recorded data from the specified address on the optical disc by overwriting the data area with required erasing data, wherein: the optical disc has a plurality of recording layers; and if, after recording data on a first layer of the optical disc, the recording controller judges a recording failure to have occurred during recording on a second layer, the recording controller focuses the optical pickup on the first layer and erases recorded data by overwriting the recording surfaces of the first and second layers at the same time at a required erasing power level.
