Document Type and Number:
WIPO Patent Application WO/2010/064305
Kind Code:
A1
Abstract:
A recording device (1) comprises: a recording means (11) for recording a data pattern by illuminating a recording medium (100) with a laser beam (LB) while changing the power thereof; a reading means (11) for obtaining a read signal by reading the data pattern; a first measuring means (23) for measuring one of the β value and asymmetry of the read signal; a second measuring means (19) for measuring the jitter of the read signal obtained by reading a data pattern in which at least one of the β value and the asymmetry satisfies a desired condition; and an adjusting means (21) for adjusting, based on the jitter measured by the second measuring means, a recording condition in the recording means.
