摘要： A magneto-optical disc recording apparatus includes a magnetic head, an optical head, a position detector and a controller. The magnetic head supplies a vertical magnetic field corresponding to recording data to a magneto-optical disc. The optical head emits a light beam to the magneto-optical disc through a substrate of the magneto-optical disc. The magneto-optical disc is arranged between the magnetic head and the optical head. The optical head has an actuator for moving an objective lens in a tracking direction. The position detector detects the displacement of the actuator. The controller controls a recording operation of the magnetic head and the optical head. The recording operation is started when a result of detection by the position detector reaches a predetermined value.

摘要： An optical recording medium is provided which has a substrate and a signal recording layer provided on the substrate and in which an information signal is recorded in the form of microscopic pits. A light beam is focused on the signal recording layer and some change of the light beam carried by a return light from the signal recording layer is detected to read the information signal recorded on the signal recording layer. The optical recording medium has a diameter of 65 mm or less and a thickness of 0.4 to 0.7 mm. An information signal recording area extends outwardly from a radial position of 12.5 mm or less from the center of the medium. The ratio in area between the information signal recording area and non-signal recording area is 3.4 or more. The storage capacity of this medium is 2 gigabytes or more. The optical recording medium has formed at the center thereof a center hole around which an annular table-abutment convexing to one side of the medium is formed. A magnetic-clamping hub is installed in the center hole and thus the medium is magnetically clamped to a rotation driving mechanism of an optical recording and/or reproducing apparatus. The compactness and high density of recording of the optical recording medium will contribute greatly to a further compact structure of a recording and/or reproducing apparatus in which the medium is to be used.
