Abstract: PROBLEM TO BE SOLVED: To enable a just-tracking even in the case of executing seeking between a land part and a groove part. SOLUTION: At the time of recording and reproducing a signal by respectively making the land part and the groove part as track areas, when a target track is not the track of the same system and a pickup is moved to near of the target track, a tracking control is performed with respect to the track at the time of starting the movement by using a land-groove signal whose polarity is inverted. When the pickup is to be moved from the land part to the groove part or when the pickup is to be moved from the groove part to the land part, the long signal is inverted. At the time of a seek mode, the land groove signal is inverted in a timing when a mode transits from an acceleration mode to a constant speed mode, Since the phase of the land groove signal is shifted by a half pitch by this inversion processing, the pickup is made to perform the just-tracking to a correspondent track.

Abstract: PROBLEM TO BE SOLVED: To control the distance between a floating magnetic head and a disk- shaped recording medium with high accuracy and high stability regardless of the materials of the disk-shaped recording medium. SOLUTION: This device has first and second optical heads 3A, 3B and driving mean for attaching and detaching the floating magnetic head to and from the recording surface of the disk-shaped recording medium 5. These first and second optical heads 3A, 3B are arranged between photodetectors 6A, 6B as well as between the photodetectors 6A, 6B and the disk-shaped recording medium 5. Light sources 7A, 7B are so constituted as to allow the transmission of the reflected light beam from the recording surface of the disk-shaped recording medium 5 and to make the light incident on the photodetecting surfaces of the photodetectors 6A, 6B. These light sources are positioned with respect to the photodetectors 6A, 6B. A high reflection film HRC is deposited on the end face 7Aa on the photodetector 6A side and an antireflection film ARC is deposited on the end face 7Ab on the disk-shaped recording medium 5 side. A high reflection film HRC is deposited on the end face 7Ba on the photodetector 6B side. The driving means is so controlled as to attain the specified distance of the floating magnetic head to the disk-shaped recording medium 5.

Abstract: PROBLEM TO BE SOLVED: To improve the quality of reproduced image by compensating for minute defects incapable of being perfectly compensated heretofore by a defect compensation part of a drive part in a DRAW optical disk. SOLUTION: A reproducing level/recording level switch part 7 switches output setting of laser beam of a laser element 4 for reproducing/for recording. A defect detection part 13 detects a defect of an optional size on a signal recording surface of an optical disk from reflected laser light. A comparator 16 compares whether or not the defect of the optical size is smaller than a prescribed threshold value. By a switch control part 18, the switch part 7 switches the output setting of the laser beam of the laser element 4 from for reproducing to for recording when the comparison result is that the defect of the optional size is the defect of the minute size smaller than a prescribed value. By a pseudo pit recording part 6, the recording laser light irradiates near the defect of the minute size on the signal recording surface in a pulse shape to record a pseudo pit equal to the defect of the prescribed size or above. A compensation part 14 compensates the regenerative signal of the defect part of the mixture size containing the pseudo pit.

Abstract: PROBLEM TO BE SOLVED: To record a signal in order to form an optical recording trace of always steady size by controlling a level of a driving pulse from a driving pulse source based on a detected phase difference. SOLUTION: A recording track on an optical disk 11 rotating at a fixed linear velocity is irradiated with a recording light beam. A part close to the recording light beam irradiating part of a recording track but separated by a prescribed distance from this irradiating part is irradiated with a reproducing light beam. A return light beam of the reproducing light beam from the optical disk 11 is detected by a photodetector of an optical head 13. A data pulse having a time width corresponding to a value of an input data (a) is generated by a generating source 5. Then, an edge of a detected pulse from the photodetector is phase-compared with an edge of the data pulse from a delay means 15 by a phase comparator means 16. The level of the driving pulse from the pulse source is controlled based on a detecting phase difference, so as to make the detecting phase difference from the comparator meand 16 a prescribed value.

Abstract: PROBLEM TO BE SOLVED: To provide an optical disk device capable of stably high density record ing even in case of over-write. SOLUTION: A generation part 23 generates a pulse train signal PT from a signal DI to control switches 24, 42. The switch 24 selects the signal RC of a read-out power control part 25 to turn the switch 42 on. A drive part 28 generates the signal LD based on the signal RC to irradiate an optical disk 10 by a laser beam. An optical pickup 32 generates the signal SD showing the state of the reflectance of the optical disk 10 based on reflected light of a side-beam precedent to a main beam. The signal SD is supplied to a delay part 43 through a filter part 41 and the switch 42. The delay part 43 delays the signal until the main beam becomes the preceding sub-beam position to supply it to an interpolation part 44 and to generate the signal HC. The signal HC is added to the signal WC1 of a recording power control part 26. The drive part 28 generates the signal LD based on the added signal AC, and controls the light quantity of the laser beam according to the reflectance of the disk 10 to perform recording.

Abstract: PURPOSE: To stably record a signal regardless of the temp. of a optical disk by incorporating a temp. sensor in the optical disk and controlling laser output with the sensor. CONSTITUTION: When the signal is recorded on the optical disk 3, a switch 66 is turned on, and a temp. detection signal TM is supplied from the temp. sensor 4 to a reference control signal generation part 62 through a sensor amplifier 65. A reference control signal BC is generated by the generation part 62 based on a reference signal RE and the signal TM to be supplied to an output control part 61. A laser drive signal DR is generated by the control part 61 based on the signal BC and a monitor signal PM from a photodetector 47 to be supplied to a laser drive amplifier 63. A high frequency signal HF is supplied from a high frequency signal generation part 64 to the amplifier 63. A laser diode LD is driven by the signal DR, and the drive (excitation) state of the laser diode LD is modulated by the signal HF. Not only the laser output of the laser diode LD is controlled based on the signal PM, but also it is varied according to the temp. detected by the temp. sensor 4. The signal is recorded stably regardless of the disk temp. of the optical disk 3.
