Plate transfer from one module to the next is a manual operation. In addition, the spiral cam 7 and the driven gear 10 are integrally attached to the rear side of the support plate 12 by a rotating shaft 16, the Asahi Optical DISK Device gear 10 is meshed with the above pinion 9 and the circumference of the spiral cam 7 abuts against the above cam follower 2h. The rotating shaft 16 is fixed to the plate 12 by means of a fixing member 16a integrally mounted on the plate For example, a recess portion 16a-1 is formed inside of the fixing member 16a and the shaft 16 is inserted into the recess 16a-1 and fixed.

Asahi Optical DISK Device order to compensate the downward shifting of the beam, the movable prism 50 is moved downward as shown in FIGS. When the movable prism 50 is moved downward, the beam reflected by the upper surface 51 of the movable prism 50 shifts to the right, so that the beam reflected by the intermediate mirror 53 shifts upward. The amount of movement of the moveable prism 50 is determined according to the equation 1so that the downward shifting of the beam caused by the rotation of the galvano mirror 26 is compensated. The above described compensation operation is also performed during the accessing process to the lower surface of the optical disk 2.

In order to compensate the upward shifting of the beam, the movable prism 50 is moved upward as shown in FIGS.


As described above, according to the embodiment, even when the galvano mirror 26 rotates, the incident position of the beam on the first lens 10 a 10 b does not vary. During the times Asahi Optical DISK Device CD writer drives, they are often marked with three different speed ratings. In these cases, the first speed is for write-once R operations, the second speed for re-write RW operations, and the last speed for read-only ROM operations.

For DVD writer drives, Blu-ray disc combo drives, and Blu-ray disc writer drives, the writing and reading speed of their respective optical media are specified in its retail box, user's manual, or bundled brochures or pamphlets. The recorder, should it run short, would be forced to halt the Asahi Optical DISK Device process, leaving a truncated track that usually renders the disc useless. These can suspend and resume the recording process in such a way that the gap the stoppage produces can be dealt with by the error-correcting logic built into CD players and CD-ROM drives. Although later interfaces were able to stream data Asahi Optical DISK Device the required speed, many drives now write in a ' zoned constant linear velocity '.

JPB2 en. The 0. Although the diameter of the outer zone appears only slightly larger than the central zone diameter, nearly 0. The ability to independently modify these outer zone surface profiles gives the designer a strong control of the DVD system aberrations that is independent of the CD system aberrations.

The two different cover plate thicknesses are shown in this figure. Method and apparatus for large spectral coverage measurement of volume holographic gratings.


Complex objective lens, the optical head apparatus, an optical Asahi Optical DISK Device apparatus and an information processing apparatus. It is noted that the semiconductor laser may be mounted on the carriage, although it may be mounted in a fixture along with a collimator lens which converts the laser beam into parallel light so that the parallel light is emitted in parallel with the tracking direction of the optical disk toward the vertical reflection mirror.

It is further noted, however, it has become a mainstream design to configure the optical pick up without a collimator lens and an objective lens to be Asahi Optical DISK Device finite optical system while the entire optical components of the optical pickup are mounted on the carriage so that the entire optical disk drive can be downsized. An example of such an optical pickup being entirely mounted on a carriage is disclosed in Japanese Patent Provisional Publication No.
