    Abstract: An optical recording medium allowing data to be recorded on, erased from, and reproduced from, and storing information about power levels of an erase pulse. The recorded erase pattern information may include information about power levels of first and last pulses of an erase pattern for erasing data. The first and last pulses of the erase pattern can be differently set depending on the differing kind of recording layer or layers of a disk or differing kinds of disks and recorded in a reproducible only area or rewritable area of the optical recording medium. Thus, by presetting the appropriate erase power levels, the time required for selecting an optimal erase power for the optical recording medium can be considerably reduced.

    Abstract: An optical disc and a method of recording essential information in and reproducing the essential information from an optical disc are provided. The optical disc includes a pattern of crystalline and amorphous marks representing the essential information. The essential information recording method includes heating an amorphous recording layer above the temperature of crystallization by radiating a laser beam according to a photoelectrically converted signal, and slowly cooling the heated recording layer to the temperature of crystallization or below to form the pattern of crystalline and amorphous marks. The essential information reproducing method includes radiating the beam onto the pattern of crystalline and amorphous marks in which the essential information of the optical disc is recorded, receiving the beam reflected from the pattern of crystalline and amorphous marks and photoelectrically converting the received beam into a detected signal, filtering the detected signal through a high-pass filter, and reproducing the essential information of the optical disc from the filtered signal. The essential information can be recorded in a recordable optical disc by phase change using a conventional disc initializing apparatus after deposition of a recording layer and before initialization of the optical disc. Therefore, an additional recording apparatus and process is not necessary, and no damage caused by a high energy of the laser beam occurs in the optical disc.

    Abstract: A recording medium storing linking type information, a method of processing a defective area in the medium and recording and/or reproducing apparatus therefor. The recording medium stores information indicating that linking is applied immediately after the defective area, distinguishing a linking type which occurs in a general incremental recording mode from a linking type which occurs after the defective area. Defective areas are detected and registered in a predetermined area (recording management data (RMD) area) before user data is recorded or while user data is being recorded in the recording medium having a plurality of continuous basic recording units, such as a digital versatile disc-rewritable (DVD-RW) in which recording and reproducing can be done repeatedly. Linking is not only applied in an incremental recording mode or in a restricted overwrite recording mode, but linking is also applied to an area immediately after the defective area which is registered in the defect list, increasing reliability of the user data. In addition, a test signal such as data, a groove wobble pattern, or a recording mark which has a test pattern, which functions as linking data is recorded in advance in a block immediately after the defective area detected during certification. If the test signal is detected after the defective area, the new user data is recorded immediately after a predetermined number of error correction code (ECC) blocks following the defective area without using linking, reducing the time for recording linking data, which is advantageous to real-time recording.
