Recording apparatus and method, computer program, and recording medium

摘要

A recording apparatus includes: a first calculating device for calculating an optimum power for recording the data pattern into a recording-scheduled area (RSA) in an inner area; a first controlling device recording the data pattern with the optimum power outside an end on an outer side of the RSA; a second calculating device calculating an adjustment power used in adjusting a recording condition outside the end on the outer side of the RSA, considering a difference between recording sensitivity inside and outside the RSA; a second controlling device recording the data pattern for adjusting the recording condition with the adjustment power outside the RSA; a reading device obtaining a read signal; a measuring device measuring read signal jitter; an adjusting device adjusting the recording condition for satisfactory jitter; and a third controlling device to record the data pattern into the RSA using the optimum power and the adjusted recording condition.
