RECORDING ADJUSTMENT DEVICE, RECORDING ADJUSTMENT METHOD, AND PROGRAM

WIPO Patent Application WO/2017/126330

A1

The present technology relates to a recording adjustment device, a recording adjustment method, and a program whereby it is possible to compensate for recording to an optical disc having a high linear density. A recording adjustment device according to an embodiment of the present technology repeats a prescribed process among the processes of: performing filtering on the basis of a reproduction signal acquired by reproducing data recorded in a recording medium and a recording pattern comprising data marks and spaces and identifying an impulse response in a system; calculating an amplitude difference between the filtering output after the identification of the impulse response and the reproduction signal for each edge type; detecting the inclination of a step response near an edge position; and calculating a correction amount for the edge position for each edge type on the basis of the amplitude difference and the inclination of the step response, correcting the edge position in accordance with the correction amount, and recording the data to be recorded onto the recording medium. The present technology can be applied in a recording adjustment device that records data onto an optical disc.
