Abstract
A magneto-optical recording method is disclosed. A first recording domain is formed by the application of light having a predetermined energy level to a magneto-optical recording medium. A portion of the first recording domain is erased to thereby form a second recording domain having a crescent shape by the application of light having an energy level less than the predetermined energy level subsequent to the application of the light having the predetermined energy level.
