摘要：
An optical recording medium comprising a substrate, an optomagnetic recording layer made of a magnetic film where information can be recorded and reproduced by irradiation with a light beam, and an optical recording layer which can be modified in optical properties to form guide tracks when information is recorded in or reproduced from the optomagnetic recording layer.
