    摘要： An optical storage medium for the storage of information is produced by employing a material (4) having a solid matrix upon irradiation with a suitable form of energy undergoes a generation or increase of gas pressure within a solid matrix. To write information in the medium, energy is directed to a localized area. The energy, if appropriately chosen, produces a desired gas pressure which deforms the surface (8) of the medium in the localized area. Indeed, if sufficient energy is applied, the gas pressure is sufficient to remove (11) the material in the localized area. Either the removal of material or the production of a surface irregularity produces an optically observable change relative to the unexposed regions of the medium. In this manner, it is possible to store information in the medium. Upon reading, using standard techniques, a high signal to noise ratio signal is obtainable.

    摘要： @ An erasable optical data storage medium including a substrate and a dual layer of a first material and a second material on the substrate. The dual layer is susceptible to expansion and contraction, to writing data thermally, to erasing data thermally and mechanically, and to reading data optically, the first material and the second material, respectively, being bonded together and remaining in the same physical state upon the expansion and relaxation of the dual layer. Methods and apparatus are also disclosed for recording data bits on the medium.

    摘要： The present invention can properly correct spherical aberration.
    An optical disk device (10) displaces an objective lens (18) so that the objective lens is displaced to a reference lens position as a reference. The optical disk device (10) controls an information light condensing point changing mechanism (55) so as to adjust the focus (FM) of an information light beam (LM) to a recording depth (X) at which the information light beam (LM) is to be applied in a state of the objective lens (18) being placed at a reference lens position SL). The optical disk device (10) controls a servo light condensing point changing mechanism (35) so as to adjust the focus (FS) of a servo light beam (LS) to a servo layer (104) in the state of the objective lens (18) being placed at the reference lens position (SL).

    摘要： Write strategy and method for writing to a compatible optical recording medium
    The present invention relates to a write strategy and a method for writing to a compatible optical recording medium (10), which results in a recorded optical recording medium (10) having the appearance of a read-only optical recording medium for most players and recorders. The invention further relates to an apparatus (1) for writing to a compatible recordable optical recording medium (10), which makes use of the write strategy. According to the invention, the write strategy has a high-power pulse (20) at the beginning of a rectangular block-pulse (21), wherein the high-power pulse (20) is adapted to cause a local melting of a substrate (85) of the compatible optical recording medium (10).

    摘要： The invention allows two-photon absorption to occur in response to a short-wavelength light beam. The recording layer (101) of the optical information recording medium (100) of the invention contains, as a two-photon absorbing material, a compound represented by general formula (1) having a hexadiyne structure that includes in the center thereof two acetylene groups connected by a σ-bond. At the time of information recording where a recording mark (RM) is formed in the recording layer (101), two-photon absorption occurs in response to a condensed, short-wavelength recording light, whereby the recording mark (RM) is formed.
