Magneto-optical recording method using laser beam intensity setting based on playback signal

A method of optical recording, comprising the steps of:

• forming magnetization reversal areas in a test recording region of an overwriteable optical recording medium;
• illuminating the magnetization reversal areas with a laser beam;
• playing back the test pattern in the test recording region as a playback signal;
• and
• setting a low level recording laser beam intensity by finding an erasure factor from the playback signal,
• wherein the step of setting the low level recording laser beam intensity includes the step of setting the predetermined erasure factor beforehand in the range of 1/2 to 1/10, and the laser beam intensity that accomplishes the erasure factor which is found from the playback signal to be smaller than the predetermined erasure factor is taken as the low level recording laser beam intensity.

A method of optical recording, comprising the steps of:

• forming magnetization reversal areas in a test recording region of an overwriteable optical recording medium;
• and
• setting a recording laser beam intensity by performing a test recording on the overwriteable optical recording medium,
• wherein the magnetization reversal areas are not erased, and the test recording is performed in this region by overwriting,
• wherein the step of forming the magnetization reversal areas includes the step of illuminating the optical recording medium with a laser beam, and
• wherein the step of illuminating the optical recording medium includes the step of using a laser beam having an intensity from 1 to 20% greater than a laser beam intensity during test recording.
