摘要： An optical recording element (4) comprising a recording medium which includes an information recording area formed at every unit in a non-continuous condition, the recording medium further including sample (2) pits disposed at intervals of a fixed distance for providing basic information about the locations of the recording units in the same track. Each sample pit comprises a plurality of pits disposed next to the sequence of the recording units so that the spacing between the pits differs from the spacing between the recording units. At least one of the plurality of pits is a long-sized inclined pit which is inclined at an angle in the range of 6 DEG to 80 DEG to a recording track. A driving system for driving the optical recording element for recording information in the non-continuous recording area or erasing information stored therein with a light beam the output of which is varied as required and checking whether said recording or erasing has been correctly performed, within a very short time in which the light beam passes through the non-continuous recording area. By using the optical recording element in combination with its driving system, the processing speed can be greatly improved and the irradiating position of the light beam at every recording unit can be correctly controlled.

摘要： A magneto-optical- recording method includes the steps of applying an external magnetic field perpendicularly onto the magnetic thin film with perpendicular magnetization of a magneto-optical recording medium and projecting a light beam onto the magneto-optical recording medium; and modulating the intensity of the light beam between the first light intensity and the second light intensity in response to the information to be recorded while shifting a spot of the light beam, thereby recording information. In the above method, the first light intensity is set such that by reducing the coercive force of the magnetic thin film with perpendicular magnetization, a magnetic domain is formed on the magnetic thin film with perpendicular magnetization, and that the magnetic domain is moved as the spot of the light beam is shifted. The second light intensity is set such that by increasing the coercive force of the magnetic thin film with perpendicular magnetization, the magnetic domain is fixed to the position.
