A method and apparatus for recording data on an optical recording medium are provided. In the method of recording data on the optical recording medium, a mark or a space is formed using a recording waveform having an erase pattern including a predetermined pulse whose high level is higher than an erase power level and whose low level is lower than the erase power level. Thus, the shape of the mark can be prevented from being distorted and be improved, which results in an improvement in the recording/reproducing characteristics.

A recording layer of rewritable phase-change material is directly overwritten by a pulsing laser spot irradiating at a writing power level, then irradiating at a lower cool-down power level during a cool-down period, and then irradiating at an erasing level with a higher power than the cool-down level. The duration of the cool-down period depends on the spot size and/or on the linear velocity of the spot with respect to the recording layer.

A gray code decoding circuit of a hard disk drive includes a servo pattern area, a data pick-up device, and a pattern detecting device. The servo pattern area has data recorded as a gray code. The data pick-up device detects the recorded data, converts it into encoded read data, and outputs the encoded read data. The pattern detecting device detects a position of the servo pattern area in response to the encoded read data and outputs a reference pulse. The gray code decoding circuit also contains a gray window generating device, a synchronous signal generating device, a gray code extracting device, and a gray-binary converting device. The gray window generating device divides the encoded read data by a division ratio, converts the divided encoded read data into gray data, outputs the gray data, and generates a first synchronous signal after counting by a system clock to a first value. The synchronous signal generating device outputs first and second window signals in response to a second synchronous signal. The gray code data extracting device outputs the second synchronous signal to the synchronous signal generating device and outputs first and second information data taken from the gray data in response to the first and second window signals, respectively. The gray-binary converting device converts the gray code of the first and second information data to a binary code.

Regular burst signals from video line (n+0) to line (n+3) are replaced by modified burst signals which function as copy prohibit signals. The phase of the modified burst signals is controlled by controlling at least one of the orthogonal vectors into which the phase of the regular burst signal is resolved, and the phase vector of the modified burst signals is equal to the average value of the phase vector of the regular burst signals in lines (n+0) through (n+3). The phase vector of the modified burst signal in line (n+2) exhibits a phase difference of 135 DEG from the phase vector of the original regular burst signal in that line and causes image disturbances when the thus-modified video signal is recorded and reproduced by a VCR. The phase vector of the modified burst signal in each of lines (n+0), (n+1) and (n+3) exhibits a difference as small as 45 DEG from the phase vector of the original regular burst signal in those lines.

When a PCM signal having a sampling frequency of 32 KHz, a quantization of 12 bits per sample, and 4 channel is to be recorded onto tape (33), the PCM signal undergoes, prior to being recorded onto the tape, such predetermined data dispersion that burst errors incurred in the reproduction operation may be compensated.

In recording and/or detecting two different marking signals on or from a record carrier, a generator for marking signals comprises at least one pulse generator which supplies marking signals in the form of two marking-pulse trains M1 and M2 having the same frequency but having different duty factors with the values k and 1-k respectively, which differ from 0.5. A detection circuit for detecting marking signals detects the duty factor of a marking pulse train M1 or M2 respectively and which supplies a specific detection signal in conformity with its detected pulse train.
