摘要:
Because conditions for recording identification data of a medium vary in accordance with the structure of different media, such as a single-layer or a multiple-layer structure, stable data recording has been a difficult task. To solve this problem, an incident side of the laser beam for recording identification data on a single-layer optical disk 5 and a double-layer optical disk 6 is the opposite side of a substrate 1 upon which user data is recorded. From this structure, even in a double-layer optical disk 6, the recording is not affected by the recording layer of a second layer 12b and the like. Therefore, in the double-layer optical disk 6, identification data of the medium can be recorded under the same conditions as the single-layer optical disk 5.

An optical information recording medium includes a plurality of recording layers, a reflectance of at least one of the plurality of the recording layers in a non-initialized state with respect to a light beam for initialization being smaller than a reflectance of the same in an initialized state with respect to the light beam for initialization. The recording layers are initialized by irradiating, among the plurality of recording layers, the recording layer positioned farther from a light beam irradiation side with the light beam prior to irradiating the recording layer positioned closer to the light beam irradiation side, so that the initialized recording layers have no initialization irregularities. In initialization, at a position at a same distance in a radial direction on the optical information recording medium, the recording layer positioned farther from a light beam irradiation side is irradiated with one light beam before the recording layer positioned closer to the light beam irradiation side is irradiated with another light beam so that the plurality of recording layers are initialized at the same time by a light beam projecting operation in which the light beams are focused at different positions. This ensures the initialization without irregularities within a short time.

An optical information recording medium having two or more information layers, wherein the irradiation of either the information layer with a laser beam converging thereon causes information signals to be recorded or reproduced; the nearer positioned information layer than the farthest information layer as viewed from the incidence side of the laser beam has a recording layer varying between two optically detectable states, and 0≦|Tc−Ta|/Tc≦0.1 where Tc is the transmittance of the nearer positioned information layer when the recording layer is in state (a) and Ta, the transmittance, when it is in state (b). This makes possible accurate accurately recording and reproduction of information onto and out of the farther information layer irrespective of whether or not any information is recorded on the nearer information layer.

摘要:
A thermosensitive recording printer is provided with semiconductor lasers 1a to 1c, a polygon mirror 7 for condensing laser light emitted from the semiconductor laser 1a to 1c as condensed spots on a recording medium 10 to perform scanning in a main scanning direction, and a control unit 9 for controlling the output of the laser light. If a ratio of a spot diameter D1 of the condensed spots in the main scanning direction and a spot diameter D2 in a sub scanning direction satisfy a relationship of D1/D2≦½ at the time of forming an image composed of a plurality of pixels on the recording medium 10 using laser light, high-speed thermosensitive recording and a recording method with an uncomplicated power control are realized without reducing the power density of the condensed spots.
