Abstract:
An optical information recording apparatus in which a rewritable optical information recording medium is used and, before recording an information signal on the optical information recording medium, test recording is carried out, the optical information recording apparatus comprises:a test signal generation means that generates an edge test signal and a power test signal; a recording means that converts the edge test signal, the power test signal, and the information signal to a recording data signal, drives a light source based on the recording data signal, and records the edge test signal, the power test signal, and the information signal on the optical information recording medium; a recording pulse edge adjusting means that adjusts edge positions of recording pulses in the recording data signal; a reproducing means that reproduces signals from the optical information recording medium; a first recording condition determination means that allows the test signal generation means to supply the edge test signal to the recording means to record the edge test signal on the optical information recording medium and determines a set value for the edge positions of recording pulses for the recording pulse edge adjusting means based on a result obtained by reproducing the edge test signal from the optical information recording medium by the reproducing means; and a second recording condition determination means that allows the test signal generation means to supply the power test signal to the recording means to record the power test signal on the optical information recording medium and determines a set value of recording power of the light source for the recording means based on a result obtained by reproducing the power test signal from the optical information recording medium by the reproducing means, wherein the second recording condition determination means determines a proper value of the recording power of the light source for the recording means based on a result obtained by reproducing the power test signal recorded with edge positions of the recording pulses whose set value is an initial value, and the first recording condition determination means determines a proper value for the edge positions of recording pulses for the recording pulse edge adjusting means based on a result obtained by reproducing the edge test signal recorded with a recording power of which the set value determined by the second recording condition determination means is the proper value.
