摘要： A method for recording and reproducing information characterized in that an information train in which synchronizing signals are arrayed at equal time intervals between information signals is recorded in an information track on a recording medium which is wobbled in synchronism with the synchronizing signals and at a frequency integral times the frequency of the synchronizing signals, that the information train recorded in the information track is read out by read-out means, and that a position of the read-out means is controlled on the basis of the information train read out. The wobbling waveform is 90.degree. out of phase with a harmonic component of the synchronizing signals.

摘要： When error detection codes are added to a sampled signal word which is a digital version of audio information and a control signal which is a digital version of system control information to construct a data frame and a control signal frame, respectively, the error detection code for the data frame is generated under an arithmetic condition different from that for the control signal frame. In this manner, frame identification information is superimposed on the error detection codes. In a reproducing unit, the error detection codes containing the identification information are used to check an error in the reproduced sampled signal word and control signal and to effect the discrimination between the data frame and the control signal frame.

摘要： In a method of recording/reproducing information associated with an apparatus and recording medium, the medium has an alternate formation including tracks of first regions wherein at least an optical record of preformatted pits at a constant time interval is recorded and second regions in which information is recorded so that optical retrieval can be achieved. A clock signal is generated based on the readout signal of the preformatted pits to record an information signal in the second regions, and the clock signal is retarded and used to read out data pits that are the record of the information in the second regions.

摘要： In a light spot position control system and method in which a control of the irradiation position of a light spot such as a focusing control, a jitter correction and/or a tracking control is made through a sampling control, a newly sampled error value is compared with a one-preceding sampled value. When a difference between both the values is within a range of a predetermined width, the newly sampled value is used as a new sample value as it is. When the difference exceeds the range of the predetermined width, a sum of the one-preceding sampled value and the predetermined width is used as a new sample value. Thereby, the influence of erroneous samples is reduced.

摘要： An optical information recording and reproducing apparatus of a sampling servo system which effects the tracking by holding the differential output of the reproduced signals of tracking pits that are wobbled toward the right and left relative to the track of the optical disk. Reproduced signals of a plurality of pits arranged maintaining a distance on the track and wobbled toward the right or left in a servo signal region, are compared with each other to detect any abnormal condition in the tracking pits. When the abnormal condition is detected, the tracking signal that is sampled is not used, but instead the tracking signal sampled under the normal condition is continuously used to perform the tracking control.

摘要： In an optical disk, one turn of a recording track is divided into a number of sectors. Each of these sectors is composed of a servo field, which is stored in advance with servo information for tracking, and a data recording area which is to be written with data. A predetermined number of these sectors are joined together to form a plurality of blocks. Each of these blocks is recorded at the data recording areas of its predetermined sectors with identification information for identifying the blocks and phase synchronization loop pull-in information for read out clocks.
