摘要： A visible light characteristic changing layer formed from photosensitive or heat-sensitive material is formed in a location which can be viewed from a part of a label surface of an optical disk. The optical disk is set on a turntable of an optical disk unit while the label surface of the optical disk is directed downward. The optical disk and an optical pickup are moved mutually along the plane of the optical disk. In synchronism with the relative movement, the power of a laser beam output from the optical pickup is modulated in accordance with image data, such as characters or graphic images to be printed, and the laser beam is emitted onto the visible light characteristic changing layer. As a result of the visible light characteristic changing layer being exposed to the laser beam, a visible-light reflectivity of the visible light characteristic changing layer is changed, thereby forming a image corresponding to the image data on the label surface.

摘要： In optical disc drive, laser diode is used, and also HFM (High Frequency Module) oscillator is used to reduce laser mode hopping noise. Big EMI noise is radiated by the HFM current for optical noise reduction, or by the switching current for write-strategy of recording. Then conventionally, shield was required in order to reduce EMI noise radiated by the current driving a laser diode. By giving a jitter to the HFM signal superimposed to the current of laser diode or switching signal by write-strategy for recording, a spectrum is diffused and the peak value of an EMI noise is reduced.

摘要： A link writing method for a recordable or rewritable compact disk includes recording a writing interruption address and enabling a succeeding writing process after the writing interruption. Enabling a succeeding writing process includes searching the linking area and enabling a start writing signal and activating a laser power. The method can link a succeeding writing area with a previously written interrupted area with sufficient accuracy to allow the data frame to be successfully processed by error correction within the host drive. The linking area may be positioned by counting the values of the interrupted block, the interrupted data frame, and the interrupted bit count or by detecting a blank area. Other techniques for positioning the linking area include detecting an unwritten area having a length greater than a maximum or writing a characteristic pattern after an interruption.

摘要： The stable reproduction of wobble signal without generating beats despite of an improvement in recording density by narrowing a track pitch is realized. Data by magnetooptical recording is recorded on wobbling grooves and lands between adjacent wobbling grooves. The wobbling grooves are provided to wobble both sides of the grooves in different amplitudes. Further, both the sides wobbled in different amplitudes are wobbled in phase in the track direction. These different amplitudes of both sides are preferably set to 3.3 to 40%.

摘要： A test recording is performed with respect to an optical disc prior to a regular recording, and a β value for setting a qualitative parameter relating to the level of the recording state within a preferable range is derived from a result of the test recording. Then, the recording velocity at which the derived β value or the writing laser power value is within the preferable value can be obtained. Therefore, the recording velocity at which the satisfactory recording can be realized with few recording errors can be determined. Further, a relation between a writing laser power value and a Δβ value is obtained from the reproduced signal from the test record area, and the writing laser power value is determined considering the Δβ value. Therefore, it is possible to determine the writing laser power value for performing a satisfactory recording even with the optical disc having a characteristic of a so-called β significant point at which the β value significantly changes with respect to the writing laser power value.
