Patent ID: 8009535

Claim:
A recording apparatus comprising: a recording device for recording a desired data pattern onto a recording medium comprising an inner area and a user data area located on an outer side of the inner area; a first calculating device for calculating an optimum power, which is used in recording the data pattern into a recording-scheduled area portion, before the data pattern is recorded into the recording-scheduled area portion which is an area portion in the user data area in which the data pattern is scheduled to be recorded by the recording device; a first controlling device for controlling the recording device to record the data pattern with the optimum power into an area portion which is outer than an end on an outer side of the recording-scheduled area portion; a second calculating device for calculating an adjustment power, which is used in adjusting a recording condition of the recording device in an area portion which is outer than the end on the outer side of the recording-scheduled area portion, in consideration of a difference between a recording sensitivity in the recording-scheduled area portion and a recording sensitivity in the area portion which is outer than the end on the outer side of the recording-scheduled area portion, by reading the data pattern recorded by the control of the first controlling device; a second controlling device for controlling the recording device to record the data pattern for adjusting the recording condition with the adjustment power into the area portion which is outer than the end on the outer side of the recording-scheduled area portion; a reading device for reading the data pattern recorded by the control of the second controlling device, thereby obtaining a read signal; a measuring device for measuring jitter of the read signal; an adjusting device for adjusting the recording condition such that the jitter measured by the measuring device satisfies a desired condition; and a third controlling device for controlling the recording device to start the recording of the data pattern into the recording-scheduled area portion by using the optimum power and the recording condition adjusted by the adjusting device.
