摘要： PROBLEM TO BE SOLVED: To attain reduction of recording time by eliminating the useless recording operation of the information in an optical disk device having a plurality of beams.
SOLUTION: The user information 54A, in which pointers are set by the execution of a pointer set program 58 according to a CPU 50, is separated by the pointers PF set for every phase and supplied to an encoder 38. In the encoder 38, the encode process based on the format of the optical disk is carried out for every block unit of the input information. Data after the process are separated by referring to the beam allocation pointers PB0, PB1, PB2 which are set for every beam. Encode data for every beam are inputted to a recording circuit 40 in parallel. When the recording signal is outputted for every beam in accordance with the inputted encode data, a laser array is emitted and the user information 54A is recorded on the disk.

摘要： PURPOSE:To quickly and surely fix a center hub on a table main body while sliding the hub easily to a normal position by adding an additive reducing a frictional resistance in between synthetic resin forming the table main body and the center hub. CONSTITUTION:Since the frictional resistance of the mounting plane of the table main body 4 on which the center hub 8 is mounted is very small, the center hub 8 is held at an original position without following up the rotation of the table main body 4. As a result, since a driving pin 7 is easily slided to the center hub 8, the driving pin 7 can be inserted into a positioning hole 11 with an absolute minimum displacement of the rotation of the table main body 4. Thus, a disk 9 is prevented from being started to rotate in a state where the position of the center hub 8 is being deviated from the normal position and the loading defect of a floppy disk is surely prevented.

摘要： PURPOSE:To miniaturize the device. CONSTITUTION:A head assembly 76 is connected via a transmission mechanism consisting of a rack 91a and a pinion 75 to a flat stepping motor 74, and this stepping motor 74 is disposed underneath a disk cartridge 3 under its inserting state. Consequently, since it is possible to make the head assembly 76 approach the middle part of an inserting position of the disk cartridge 3 in its widthwise direction, the size of depth and the size of width of a case 71 can be shortened.

摘要： PROBLEM TO BE SOLVED: To accurately execute a process intended by a user according to a user's motion.SOLUTION: An image processing part 17 detects a user position showing a position of a user that is shown by values on several different coordinate axes. A mode processing part 19 calculates user motion information showing the user's motion based on a coordinate point defined by at least one value on an axis among the values on the several axes showing the user position, determines a process to be executed from several processes executed according to the user's motion based on the calculated user motion information and executes the determined process. This invention can be applied to, for example a detector detecting a three-dimensional position of a user.

摘要： PROBLEM TO BE SOLVED: To properly perform focusing on a target recording layer even when stray light is generated.
SOLUTION: Distance information including tolerance from the surface of an optical recording medium to a recording layer and position-drive value correspondence information indicating the relation between a focal position of a laser beam and a focus drive signal value with a medium attachment surface as the reference are stored. On the basis of the distance information and the position-drive value correspondence information, a focus drive signal value when a focusing position of the laser beam is at a lower limit position of the recording layer and a focus drive signal value when it is at an upper limit position are obtained, and the sections other than the section between the focus drive signal values are set as masked sections with respect to a reflected light signal. Accordingly, when performing the focus-on operation, a servo pull-in object section corresponds to that from the lower limit position to the upper limit position of the recording layer, thereby preventing the focus servo pull-in from being performed from an incorrect S-curve signal accompanying the stray light.

摘要翻译：要解决的问题：即使在产生杂散光时，也能适当地对目标记录层进行聚焦。解决方案：包括从光记录介质的表面到记录层的公差的距离信息和指示激光束的焦点位置与聚焦驱动信号值之间的关系的位置驱动值对应信息与介质附着表面作为参考存储。基于距离信息和位置驱动值对应信息，当激光束的聚焦位置处于记录层的下限位置时的聚焦驱动信号值，当处于获得上限位置，并且除了聚焦驱动信号值之间的部分之外的部分被设置为相对于反射光信号的屏蔽部分。因此，当执行对焦操作时，伺服引入对象部分对应于从记录层的下限位置到上限位置的对象部分，从而防止从不正确的S执行聚焦伺服拉入伴随杂散光的曲线信号。版权所有（C）2009，JPO＆INPIT

摘要： PURPOSE: To prevent a cassette holder in empty state from falling to a cassette loading position and to prevent the occurrence of collision among heads by detecting the insertion of a cassette by a cassette detection mechanism and allowing the down movement of the cassette holder. CONSTITUTION: When a disk cassette is inserted into a cassette holder 3, a pin 63 is activated, the restraint of a cassette detection mechanism 56 and an engagement pin 68 is released, an up and down operation plate 2 is guided by a pin 55 and a long hole 66 and pushed to a forward direction by a spring force. The motion of the plate 2 is transmitted through a tilt guide 36 and a roller 4. The holder 3 holds a disk cassette, is led by a guide groove 5 and moves down to a cassette loading position from a cassette insertion position. If a disk cassette is not inserted into the holder 3, a lock arm 12a of a shutter open and close lever 12 stops the displacement of the mechanism 56 and the movement of the plate 2 caused by the collision during a transportation is prevented.
