TL;DR: In this article, the authors proposed an image display device consisting of a light source for emitting light modulated corresponding to information, a scanning element 10 for scanning incident light at least in one direction and an optical system 2 for guiding the light emitted from the light source to the scanning element.

TL;DR: In this article, a polarizing beam splitter is used for branching a laser beam from the laser light source into a first optical beam for reproducing information recorded on an optical disk and a second light beam for canceling noise from the light source, and a reproducing signal light receiver is designed to use the laser-light- source-noise canceling signal obtained by the second laser beam and to carry out a noise canceling arithmetic operation for the purpose of removing noise contained in the reproducing signals.

TL;DR: In this article, a content reproduction system is proposed to provide a continued reproduction processing of content between various output apparatuses conveniently, where a HDD recorder is instructed to perform reproduction so that, by using the content-reproduction-history information 71 and the inter-apparatus linkage-system information 61, content that has been reproduced and output to a television apparatus 1 can be continuously reproduced and can be output to the television apparatus 2 by a technique considering the interaccess linkage system information 61.

TL;DR: In this article, the authors proposed a method to shorten the recording time by simultaneous verification at the time of recording by using a returning light from the reproducing layer at the same time.
