摘要： Method and apparatus for optically detecting information from a recording medium in which pits are formed by thermal energy of a light spot to record the information. A reproduction spot is irradiated onto the recording medium to produce a detection signal. From a differential signal of the detection signal, a signal indicative of zero points of the differential signal and a signal indicative of the presence of the pits are detected, and both the signals are used to detect positions of the pits. For stable and accurate detection of the pit position, the relation between pit size W and reproduction spot size W.sub.s is prescribed and the pit size and reproduction spot size are so set as to satisfy 0.45.ltoreq.W/W.sub.s .ltoreq.0.75.

摘要： An optical recording medium on which information is recorded by irradiating the medium with a light spot to cause a characteristic change of an actual reflection factor, the optical recording medium including grooves of different optical depths which extend in a direction in which the light spot is moved relative to the medium and which are alternately and periodically formed in a direction perpendicular to the relative movement direction of the light spot so that a plurality of grooves thereof can be covered by the light spot, and mark recording regions provided on the flat surfaces between the grooves, the pitch of the flat surfaces between the grooves being selected to be substantially half the diameter of the light spot, thus increasing the recording density and preventing the cross-talk. A method and apparatus for reproducing the information recorded on the medium are provided. Of the reflected and diffracted light distribution obtained by irradiating the light spot on the optical recording medium, the intensity change of the 0-order and third-order interference regions on the shallow groove's side are detected in the form of electrical signals, and information signals corresponding to mark are reproduced on the basis of the detected signals.

摘要： When recording domains are formed locally on a recording medium and information is recorded and reproduced by using rise and fall in a reproduced waveform obtained from the recording domains as data, timing patterns indicating start of demodulation are recorded for the lead-edge and the tail-edge of the recording domains, respectively; time interval between the timing signal for starting demodulation detected from the rise in the reproduced waveform and the timing signal for starting demodulation detected from the fall in the reproduced waveform is detected; time shifts of the signals detected from the lead-edge and the tail-edge of the recording domains succeeding the timing patterns for starting demodulation by using the time interval thus detected; and the information is stably detected as time sequential data having no jitter.

A recoding area of the recording medium is constructed with a plurality of zones and each zone is different in a sector number per one round of track. A number of the recording units for conducting a verify control for each of the zones is changed on the basis of a number of sectors per one round of track and a number of sectors for turning back by the one round of track.

摘要： In an optical information recording/reproducing apparatus, in which two sets of circuits (including a comparator 104 and a time counting device 105 (i.e., pulse width detector), and a comparator 110 and a time counting device 111 (i.e., pulse width detector)) are provided for detecting that the fluctuation larger than a comparison level continues in the TE signal for a time period, each being set at the respective comparison level and the time duration, differently, thereby the operation of write or erase onto an optical disc 101 is stopped even if only one of them is detected. Also, a position or location information in the PID portion to be reproduced, being outputted from a PID register 107, and a location information which is read out by the PID decoder 106 are compared by a comparator 108, thereby stopping the operation of write or erase onto the optical disc 101 if they are inconsistent with.
