摘要： In a magnetooptical recording medium comprising a first dielectric layer, a recording layer, a second dielectric layer, a metal reflective layer, and a protective coat on a substrate, magnetooptical recording is carried out in a magnetic field modulation mode using recording light. The first dielectric layer is thinner than the thickness corresponding to the primary minimum reflectivity in the reflectivity versus thickness curve of dielectric layer measured at the light wavelength. This provides an increased recording sensitivity and an increased recording power margin over which recording/reproducing operation can be carried out at low error rates and high resolution.

摘要： An optical head device (optical head) for a multi-layered optical recording medium has a focus control mechanism that makes use of astigmatism. The focus control mechanism has a sensor lens that includes a cylindrical lens. The focus control mechanism causes a light beam having passed through the sensor lens to have astigmatism, thereby being focused linearly in the Y direction on a front focal line located closer to the sensor lens and focused linearly in the X direction at a rear focal line located farther therefrom. The optical head also includes a photodetector which is disposed between the front focal line and the rear focal line to detect a focal position from the shape of a light beam. At the position of the front focal line, a shield plate with a window portion is disposed. The window portion has a size so as to allow the focal line to pass therethrough and shield stray light reflected from an unfocused recording layer.
