Abstract: An optical recording method for recording data on an optical disc by using a laser beam. When an optical disc is inserted into an optical recording device (step S1), a power calibration area (PCA) is searched so as to be used for optimum power calibration (OPC) on the optical disc. At the position found, an optical pickup is made to wait (step S4). After this, when a data recording operation input is received (step S6), the OPC operation is executed at the wait position (step S7) and optimum power is obtained. After this, the optical pickup is moved to the data recording area of the optical disc (step S10) and data is recorded in the data recording area of the optical disc by the optical pickup (step S11).

Abstract: PROBLEM TO BE SOLVED: To provide an optical pickup and optical recording medium driving unit with a simple and compact configuration for detecting a proper track error signal in which effect of a stray light between layers is reduced.
SOLUTION: The optical pickup comprises photo detectors 9 and 10, and generates the track error signal Tr according to (A-D)-ma((B1+B2)-(C1+C2)) (ma is a coefficient set based on a ratio of tilt of a DC offset corresponding to a lens shift in the radial direction) based on a differential signal (A-D) of light receiving signals A and D from a split light receiving element of the photo detector and a differential signal {(B1+B2)-(C1+C2)} of each sum signal of the light receiving element signals B1 and B2 and C1 and C2. Especially when recording or reproducing one of the recording layers of a double layer disk, the coefficient ma is corrected to be smaller than the correction coefficient set based on the ratio of the tilt of the DC offset corresponding to the lens shift in the radial direction.

Abstract: PROBLEM TO BE SOLVED: To improve the operability when air-checked contents are reproduced. SOLUTION: Among various types of information data which are character information data which are read out at the time of reproduction, the character information data corresponding to title information data are identified as specific types. As the title information data are transmitted when the broadcast of a music is started and recorded simultaneously, the address of the sound data of the starting part of a certain music can be estimated from an address in which the title information data are stored. Therefore, if program segmentation points TM1-TM4 are set in accordance with the address of the title information data concerning the recorded broadcast sound, one track as the recorded broadcast sound is edited and divided into a plurality of tracks (TK1-TK5) at the starting point of the music. With this constitution, the starting point of the music can be accessed at the time of reproduction afterwards.

Abstract: PROBLEM TO BE SOLVED: To improve operability at the reproduction of contents recorded by air check. SOLUTION: A reception timing for text information in a specific form corresponding to music name information among various kinds of text information is identified. The music name information is transmitted at the start of broadcasting of the music, and therefore the reception timing corresponds to a timing at which the music is started in the broadcasting. In recording the broadcast sound, therefore, points (addresses on the disk) corresponding to the timings are made program separation points TM1-TM4, whereby the track on which broadcast sound is recorded is divided to tracks (TK1-TK5) by the start points of the music, thus enabling an access to the start of the music at the reproduction time.
