摘要： When user data is recorded on a write-once medium, linking variations can be reduced that are produced as management information for managing the user data is updated by additionally recording on and off, thereby assuring the reliability of the reproduction compatibility of the DVD player.Before the final file of the management information is recorded, dummy data of a plurality of successive blocks are recorded at a time by a single operation, and then the final file is additionally recorded after the dummy data. Therefore, the linking precision can be prevented from being degraded in the linking portions of the management information, and thus the management information can be properly read when the DVD player makes compatible reproduction of the medium.

摘要： In a microcomputer included in an image device, a mask 2D 3D converting section expresses coordinates of a 2-dimensional image plane defined by an imaging element having a rectangular contour in a 3-dimensional coordinate system. The image plane is positioned in the state that a focal length corresponding to a zoom position is adopted as a Z coordinate value of the image plane in the 3-dimensional coordinate system. A mask display position calculating section 165 calculates a 2-dimensional position of a mask on a camera screen by utilizing a similarity of the size of the image plane and the size of the camera screen when a position of a mask on the image plane in the 3-dimensional coordinate system after PAN, TILT rotations and a zooming is converted into the 2-dimensional position of the mask on the camera screen.

摘要： An optical disc apparatus capable of restraining thermal deformation of an optical disc due to transmission of a heat from a spindle motor to the disc, comprises a turn table rotated by the spindle motor, for holding the disc, a bearing portion provided in the spindle motor, for holding a rotary shaft of the table, and a cooling element provided at the outer periphery of the bearing portion, for thermoelectrically cooling the bearing portion. The bearing portion can be directly cooled by the cooling element. Since the heat from the spindle motor is transmitted to the table through the bearing portion, the heat generated from the motor can be prevented from being transmitted to the table by cooling the bearing portion, and further, the table can be cooled. Thus, no heat is transmitted from the table to the optical disc, thereby thermal deformation of the optical disc can be retrained.

摘要： There is provided an optical disk apparatus that can inhibit, during recording or reproduction of data on or from an optical disk, a side runout that may occur in the optical disk in its circumferential direction as a result of Coriolis force when a disk rotating shift is subjected to procession movement, thereby allowing recording and reproducing quality to be stabilized and a reduced size of the apparatus. The disk apparatus provided has pressure pawls arranged at intervals smaller than those in the prior art, each of which is provided with a plurality of pressing points arranged at intervals larger than those in the prior art. Particularly, an interval between the pressure pawls is an acute angle in terms of the center angle of the disk. An interval between the pressing points is an angle of 35° or larger.
