摘要： In the past there has been a problem that on a detection surface the influence of interference causes a defocusing signal to degrade, narrowing the range in which spherical aberration can be stably detected. Accordingly, a diffraction grating is used to focus the inner and outer sides of luminous flux on separate optical detectors before the optical flux is focused on an optical detector and defocusing signals are independently calculated to find the difference therebetween, thereby providing a spherical aberration signal. This makes it possible to detect spherical aberation signals more stably.

摘要： An optical information recording/reproducing method includes that information is recorded on a rotary disk in an optically discriminative form, a light emitted from a light source is focused on the surface of the disk to form a light spot, the information is scanned with the light spot relative thereto in a rotating direction of the disk, and a reflection light or transmitting light from the disk is collected by an optical system to record or reproduce the information. An optically discriminative first information mark having a frequency higher than a spatial frequency resolvable by the optical system is recorded on the surface of the disk, an optically discriminative second information mark having a spatial frequency component higher than that resolvable by the optical system is overwrite-recorded on the first information mark, and a frequency component which is prepared from the first and second information marks and which is higher than the spatial frequency resolvable by the optical system is converted into a spatial frequency component detectable by the optical system.
