Embodiment approach 1

[0054] figure 1 An exemplary configuration of an information processing device according to Embodiment 1 of the present invention is shown.

[0055] The information processing apparatus is configured to perform at least one of a recording operation and a reproducing operation on the information medium 1 .

[0056] Information medium 1 has a structure in which transparent substrate 3 and transparent substrate 4 are bonded via information layer 2 . A visible information layer 5 is arranged on a transparent substrate 3 . The information layer 2 is configured such that recording and / or reproduction (hereinafter referred to as "recording / reproduction") of a desired information signal can be performed. The visible information layer 5 is configured such that visually recognizable visual information can be recorded. Thus, the information medium 1 comprises an information layer 2 and a visible information layer 5 facing the information layer 2 .

[0083] image 3 An exemplary configuration of an information processing device according to Embodiment 2 of the present invention is shown.

[0084] In this embodiment mode, an exemplary structure in which the first light source 6 and the second light source 7 emit light alternately is described.

[0085] will be described below image 3 The function of each element is shown in the

[0086] The first light source 6 emits a light beam. The light beam emitted from the first light source 6 is reflected by the reflective film of the first beam splitter 8 . The reflected light is converted into a collimated light beam by the collimating lens 10 . The collimated light is directed in the direction of the optical axis of the converging lens 12 through the mirror 11 . As a result, a light spot is formed on the information medium 1 by the condensing lens 12 .

[0087] The luminous power in the first light source 6 is monitored by using the power detector 13 to detect the part of t...

Abstract

The present invention relates to an apparatus capable of optically recording information onto an information medium (1) by converging a light beam which is emitted from a first light source (6) and passes through a first beam-splitter (8) and a collimating lens (10) onto the information medium (1) using a convergence lens (12) and converging a light beam which is emitted from a second light source (7) and passes through a second beam-splitter (9) and a collimating lens (10) onto the information medium using a convergence lens (12). When visual information such as a title and an image relating to information recorded in the information layer (2) of the information medium (1) is recorded onto the visual information layer (5) of the information medium (1), the first light source (6) and the second light source (7) emit light simultaneously, thereby improving emission intensity. This enables changing the color of the visual information layer which is made by heat-sensitive recording materials, thereby improving a recording speed of the visual information.

Description

field of invention [0001] The present invention relates to an information processing device capable of recording information signals on an information layer of an information medium, or reproducing information signals recorded on an information layer of an information medium, and further recording information signals of visually recognizable visible information. technical background [0002] The technique of converting an information signal into a digital signal and recording the digital signal started from an optical disc known as a CD-R, which has a dye as a main component in a recording layer. The dye was formed on a transparent substrate with a thickness of 1.2 mm. Currently, known optical discs having a recording capacity larger than that of CD-R, such as DVD-R, DVD-RW, DVD-RAW, etc., have been widely used. In these discs, transparent substrates each having a thickness of 0.6 mm are bonded together via a recording layer with a dye or a phase-change material. [0003] ...
