Abstract
A process for recording information on a magneto-optical recording medium according to a (2, 7) RLL modulated signal includes a step of setting an optical power of a laser beam to a high level state in response to a logic value '1' and a step of alternately switching the optical power of the laser beam between the high level state and a low level state in correspondence to a logic value '0' except for the bit that is immediately adjacent to the bit of the logic value '1.'
