    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 recording medium has a user data area and a lead-out area each having grooves and lands formed thereon. Wobbles are formed on at least one lateral surface of the grooves of the user data area and the lead-out area, and configured such that wobble characteristics are made different between the user data area and the lead-out area. Different types of the wobbles are formed on the grooves of either the user data area or the lead-out area, thereby preventing an optical pickup that performs recording/reproducing, from deviating from the user data area. Also, in a multi-layer optical recording medium, a whole area of a recording layer is configured to have the same condition, thereby preventing deterioration in reproducing and/or recording due to a difference in light power transmittance of another recording layer.

    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 method of and an apparatus for modulating data to be resistant to channel distortion. A space extending encoder performs a first code transformation to extend a run length of digitized data to a predetermined length and outputs the space-extended data. A multiplexer multiplexes the space-extended data and data transformed by a predetermined second code transformation. A format converter converts the multiplexed data into a predetermined format which is suitable for writing to a recording medium. The apparatus and method enable recorded data to be resistant to channel distortion, enable the data to be recorded with increased recording density, and enable the data written to the recording medium to be reproduced with improved reliability.
