摘要： A pit edge interval correcting method in an optical recording/read-out apparatus wherein as data items to be used to correct pit edge intervals for cancellation of a thermal interference from a previously recorded pattern, there is formed a table representing relationships between kinds of record patterns and edge shift quantities of the patterns in a read-out signal. Edge shift quantities of particular patterns with respect to a unitary variation quantity of a recording medium surface temperature (an ambient temperature of an optical disk) and edge shift quantities of particular patterns with respect to a unitary variation quantity of laser power are beforehand acquired as correction control data. Before actual data are recorded, the particular patterns are again recorded on a medium and read out therefrom. If an edge shift occurs in a read-out signal, a variation quantity of the recording medium surface temperature and a variation quantity of the laser power are separately obtained based on a quantity of the edge shift occurring and the correction control data collected in advance. Using each variation quantity, the value set to the laser power is altered and/or the data in the table are updated to correct the actual data.

摘要： An optical recording control method determines an optimum recording laser power by effecting a test recording before information to be recorded is recorded on a disk. The recording laser power is formed of a plurality of powers. A relationship among the plurality of laser powers is regulated by power level ratios between respective powers, whereby a power used when a laser light is radiated on the disk can be controlled to be constant independent of an ambient temperature and a structure of a disk. Therefore, accurate recording marks can be formed on the disk.

摘要： When record marks are recorded on a recording medium while making a code symbol "1" of data by obtained coding write information according to a coding system having no DC free property correspond to every edge of the record marks, the recording is effected while inserting resynchronizing signals into the write information with a constant interval. For the resynchronizing signal either one selected between a first resynchronizing code pattern, in which the number of symbols "1" contained therein is even, and a second resynchronizing code pattern, in which the number of symbols "1" is odd, so that an accumulated charge obtained from the run length of the coded data approaches zero is used. Each of the first and the second resynchronizing code pattern contains at least a specified pattern, which doesn't meet the coding rule. The selection is effected by adding a run length switching code to the resynchronizing signal and by switching it to "0" or "1" depending on an output of a run length measuring circuit and a run length judging circuit. In this way it is possible to suppress fluctuations in the level of a reproduced signal obtained from the record marks recorded on the recording medium and to realize a stable data detection by using the original waveform detection method, by which the reproduced signal is converted into a binary signal by using a suitable slice level.

摘要： An optical method for recording, reproducing, and erasing a digital signal of a mark length recording system onto/from an optical recording medium such as an optical disc or the like eliminates a fluctuation of the edge position of the reproduction signal due to heat interference between pits, thereby reducing a fluctuation of the edge position due to a fluctuation of external environmental conditions. For this purpose, there are proposed the following methods: 1) the shape of the recording pulse waveform is controlled, 2) the density at which data is recorded to the disc is variably set in accordance with the disc position, 3) a test recording is executed prior to recording user data, and the like. With these methods, a superhigh density optical recording can be realized.

摘要： In a write control method on an optical recording, at least one shift amount selected from the defocus amount of a laser beam on a recording medium, the shift amount of a recording position on a recording track and the shift amount of laser power during recording is controlled such that the selected amount falls within a predetermined range. Subsequently, a trial signal is trially recorded at a plurality of trial zones on the recording medium by using a laser power value as a parameter. The recorded trial signal is read and a difference .DELTA.V between center levels of a highest density waveform and a lowest density waveform is detected. In connection with each trial zone, the laser power value when a reading trial signal which makes the difference .DELTA.V minimum is recorded is defined as an optimum recording power value. Regular data is recorded at a predetermined storage area on the recording medium by using an optimum laser power value determined in connection with a trial zone closest to the predetermined storage area.
