Abstract: PROBLEM TO BE SOLVED: To obtain reproducing compatibility and high tone quality without shortening a recordable program time by recording the second data on a data recording medium with displacement from a track center in the direction intersecting with a track direction of a pit and making the displacement within the prescribed amount of the range not off-tracking. SOLUTION: An A/D conversion circuit 10 outputs the audio data DA of 20 bits parallel from an audio signal SA, and a bit operation part 11 analyzes the audio data DA to the audio data D2U, D2L of upper side 16 bits, lower side 4 bits, and a data processing circuit 12 generates the audio data D2U, D2L to the channel data D3, the displacement control data D4 corresponding to a pit line. A drive circuit 13 records the channel data D3 on a disk master disk 2, and the drive circuit 7 records the audio data D2L by the displacement from the track center of the pit according to the displacement control data.

Abstract: PROBLEM TO BE SOLVED: To realize an optical recording medium with less pitch unevenness in recording information, with high recording density and a high transfer rate capable of narrowing an interval between pitches. SOLUTION: In a master disk exposing device 1 for the optical recording medium, a beam position detecting means 10 detecting positions of exposing laser beams La and Lb and a beam position correcting means 20 setting the positions of the exposing laser beams La, Lb. Thus, the positional deviation of the exposing laser beams are corrected, and the interval between beams is head constant when plural exposing laser beams are used.

Abstract: PROBLEM TO BE SOLVED: To provide a disk-shaped recording medium formed with pit sequence indicating prescribed information by wobbling. SOLUTION: A pit sequence 31 formed by wobbling in a diametral direction in accordance with the prescribed information and a groove 32 formed broader than the width of the pits by wobbling in accordance with a prescribed frequency (22.05kHz) are formed on a disk. Data are recorded in these grooves 32. Since the pit sequence is formed by wobbling, the recording of the prescribed information in addition to the information of the pits is made possible.

Abstract: PROBLEM TO BE SOLVED: To increase a recordable data volume by including position information in wobbling information. SOLUTION: A wobbled group 2 is formed on a disk beforehand. A width w of the group 2 is specified as not less than a half of a track pitch q and smaller than a diameter of a reproducing beam spot. Information is recorded onto a recording film 3 on a bottom face of the group 2. The information is reproduced from a summation signal of a detector divided in the radial direction, and a tracking error is formed from a differential signal of this detector. Also, the wobbling information of the group 2 includes absolute time information as clock information and position information, and this position information can be taken out of a push-pull signal.

Abstract: PROBLEM TO BE SOLVED: To obtain a disk-shaped recording medium capable of reproducing good reproducing signals and wobbling signals. SOLUTION: Wobbled grooves 2 are previously formed on a disk. The width (w) of these grooves 2 is set at >=1/2 the track pitch (q) and smaller than the diameter of a reproducing beam spot. Information is recorded on the recording films 3 on the bases of the grooves 2. The width (w) and depth (d) of the grooves are set at the relations (9/16)q

Abstract: PURPOSE:To suppress conspicuousness of black level between phosphors so as to improve contrast by having phosphor material in which powder consisting of electrical conductive material of inorganic material having light absorption ability is mixed applied to a phosphor surface panel. CONSTITUTION:This thin flat display is constructed by having phosphor material 10 in which powder 11 consisting of electrical conductive material of inorganic material having light absorption ability is mixed applied to a phosphor surface panel. Irregular reflection of phosphors 10 at a non-luminous part is suppressed so as to suppress conspicuousness of black level by mixing powder 11 including colored electrical conductive material. A thin flat display with high contrast is obtained by suppressing conspicuousness of black level in the thin film flat display specially using an electrolic-emission type cathode. Good contrast is obtained by using Y, B, Ta, CdTe and C2S for as this powder 11.

Abstract: PURPOSE:To obtain a laser apparatus for measuring a length which can execute highly-precise measurement of the length with ease in a short time. CONSTITUTION:A laser light is applied through an optical system 4 to a magnetic head material 24 in the course of machining and the existence or nonexistence of a track groove 24a is detected from the intensity of a reflected light thereof by a measuring detector 44. At the same time, a work stage 23 whereon the material 24 is set is moved, the amount of movement thereof is detected by a laser scale 27 and the width and the pitch of the track groove 24a are measured.
