ABSTRACT:
A test-writing recording control method of the present invention forms a first recording pattern consisting of a combination of a first microarea in a first state, which is one of a recording mark or a non-mark section, and a second microarea in a second state, which is the other of the recording mark or the non-mark section and is shorter than a light beam diameter, and a second recording pattern consisting of a combination of a third microarea in the first state, which is longer than the first microarea, and the second microarea, to an optical recording medium by emitting a light beam, and sets a recording condition so that a level difference between reproduced signals corresponding to the first recording pattern and the second recording pattern becomes minimum. This makes it possible to set the recording condition for averaging heat interference in different recording patterns and to accurately record information.
