摘要： The compatible type optical pickup device is capable of recording and reproducing optical disks in different disk substrate thickness such as BD and HD DVD or the like. In more detail, an optical pickup can record and reproduce the media of two or more kinds in different substrate thickness using almost identical wavelength or the identical laser source. One is provided as the infinite type optical system and the other is provided as the finite type optical system using an expander lens. Accordingly, the optical disks of different substrate thickness such as BD and HD DVD can be recorded and reproduced with compatibility using the identical wavelength of light.

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： To permit reproduction of a CD-R and the reproduction of a DVD in a compatible manner, both the aberration introduced by a substrate of a DVD having a 0.6 mm thickness and the aberration introduced by a substrate of a CD having a 1.2 mm thickness are reduced by a lens shape design where corresponding substrate thicknesses of the inner and outer regions of the objective lens are made different, and providing, in the inner region thereof, a protruding circular phase shifter and, also in a verge of the inner region, an annular phase shifter. The aberration of the objective lens in the CD reproduction was further decreased and the NA was increased up to 0. S, so that the recording of the CD-R was made possible.

The height h is determined so that the chromatic aberration W becomes equal to or less than &lgr;/4.

摘要： Provided are highly reliable information processing equipment enabling a high recording density, and a blue color, blue-violet color and violet color based semiconductor light emitting device operable at a low threshold current density, which device is suitable for the information processing equipment. According to the present invention, there can be realized highly reliable optical information processing equipment enabling high recording density, which is capable of sufficiently recording or reproducing a dynamic image in or from a high-definition TV. An n-type impurity is doped in a barrier layer of a quantum-well active layer of a semiconductor light emitting device at a high density. Alternatively, the oriented plane of a quantum-well active layer of a semiconductor light emitting device is inclined from the (0001) plane, whereby the threshold current value of the semiconductor light emitting device can be reduced. The semiconductor light emitting device is represented by a gallium nitride based compound semiconductor laser device.

摘要： The optical disk medium permits an increase in recording density using a complex refractive index variation of an inorganic oxide film in a super-resolution medium using an inorganic oxide film. The reflectance of the disk increases due to the complex refractive index variation of the inorganic oxide film. Specifically, in the case where the inorganic oxide film is an oxide film comprising Co, a reflect addition film is provided. The effective spot diameter used for read-out is reduced, thereby increasing recording density. By using a material for which the complex refractive index varies sharply, the recording density can be approximately doubled.
