摘要： A method for evaluating an anti-contamination level on a surface of optical recording medium is disclosed. The method includes forming an artificial fingerprint on the surface by contacting a stamp having an artificial material adhered thereto on an optical recording medium, and measuring a symbol error rate (SER) of the formed artificial fingerprint, to determine a sensitivity of the fingerprint and determining whether the optical recording medium is of good quality or bad quality depending upon the measured SER.

摘要： A recording method for a phase change optical disk is disclosed. To prevent crystalline material from growing at the leading portion of predetermined marks, e.g. marks 4T or more in length, the interval between the first pulse and multi pulses among write pulses for forming marks 4T or more in length is increased by delaying the multi pulses against a reference clock and the widths or levels of the multi pulses are also increased. In another embodiment, to prevent a change in the starting positions of marks due to the increase of the interval between the first pulse and multi pulses, the last pulse among write pulses for forming marks 3T or more in length is advanced by a predefined time period. In still another embodiment, the interval between the first pulse and multi pulses among write pulses for forming marks 4T or more in length is increased and the starting position of the first pulse, the starting position and width of the last pulse, a trailing edge cooling time deviation are individually adjusted depending on the length of marks.

摘要： The disclosure includes a system, device, apparatus and programmed medium of measuring thickness of an optical disc by using an interference effect of the optical disc layer. Such a system can include: a spectroscope to separate light, reflected from a surface of an optical disc, into constituent frequencies thereof; an optical intensity measuring unit to measure intensities of the constituent frequencies, respectively, as a first spectrum of data; and a processor to do at least the following, convert the first spectrum data into a second spectrum of values that exhibits variation as a function wavelength and refractive index, transform the second spectrum using a Fast Fourier Transform, and detect a thickness of one or more of the spacer layer and the cover layer, respectively, based upon the transformed spectrum. The disclosed technologies have advantages for high precisely measuring thickness of an optical disc.
