摘要： An optical communication device includes a light source that emits a light beam and an optical fiber having a core and a cladding. The optical fiber has a light entrance face having a core region and a cladding region. The light beam emitted by the light source is converged by a converging lens on the core region and is transmitted through the optical fiber. The entrance face is configured to generate a light intensity distribution in light reflected by the light entrance face depending on a position where the light beam is incident on the entrance face, a converging lens arranged between the light source and the optical fiber.

摘要： The objective lens has a numerical aperture NA=0.6 when reproducing a DVD having a thickness of 0.6 mm and NA=0.42 when reproducing a CD having a thickness of 1.2 mm. At a boundary of NA 0.42, a slight stepped portion is formed so as to establish a phase difference. In this case, a designed wavelength is 0.635 .mu.m, and an optimum designed substrate thickness of a central portion is approximately 0.8 mm. While the DVD is reproduced, wave front aberration is on the order of 0.025.lambda., and jitter contained in the reproduction signal of the CD is equivalent to the present jitter. As a consequence, such an objective lens and an optical head with employment of this objective lens are provided, which precisely reproduce signals from the CD having the substrate thickness of 1.2 mm, and the DVD having the substrate thickness of 0.6 mm.

摘要： An information recording medium includes an information recording layer on which at least information is to be recorded by irradiating light, and a light transmission restricting layer which has a plurality of nonlinear transmission characteristics or nonlinear reflection characteristics for the intensity of the light irradiated and which has an optical material for restricting the transmission or reflection of the light according to the respective characteristics when the light is irradiated onto the information recording layer. An information recording and reproducing unit uses the information recording medium and includes an information recording position setting unit for deciding a position at which information is to be recorded on the information recording medium by detecting a direction of an easy magnetization axis. With the above arrangement, the spot diameter of the light can be distinguished between the one when information is reproduced and the one when information is recorded on the information recording medium respectively, to thereby ensure an accurate positioning of the head on the tracks of the recording medium.
