Abstract: PURPOSE:To obtain a tacking error signal of a zero-order beam unchanged by a change in a tangential skew angle to a recording medium by providing a light shield so that both side beams of a reflected beam of a recording medium are not made incident to an irradiated end face. CONSTITUTION:When a straight line connecting a center beam La and both side beams Lb, Lc toward a semiconductor laser element 1 is nearly orthogonal to an active layer 1d, for example, the light shield 9 is provided by prolonging a part of a heat sink 8, a window 9a is formed to a part of the active region 1d to the laser beam irradiating part to ensure the irradiation of a laser beam L. Then the beam reflected on a recording medium 6 and going to the semiconductor laser element 1 through a diffractive grating 3 is reflected irregularly in the light shield 9. Thus, the tracking error signal of the zero-order beam of a head OH unchanged by a change in a tangential skew angle to the recording medium is obtained.

Abstract: PURPOSE:To obtain a tracking error signal of the zero-order beam unchanged by a change in a tangential skew angle to a recording medium by adopting a shape of semiconductor laser element where both side beams of a reflected beam of the recording medium is not made incident to an irradiated end face. CONSTITUTION:When a straight line tying a center beam La and both side beams Lb, Lc toward the semiconductor laser element 1, for example, is nearly orthogonal to an activated layer 1d, the thickness of the smiconductor laser element 1 is made thin as 80mum so that the beam Lb of both the side beams is not made incident to a beam irradiating end face 1A. Further, the lower beam Lc is incident to a heat sink 8, where it is reflected irregularly. Thus, the beam reflected on the recording medium and going toward the semiconductor element 1 through a diffractive grating 3 is not reflected on the irradiating end face 1A and the tracking error signal of the zero-order beam of an optical head OH unchanged by the tangential skew angle to the optical recording medium is obtained.

Abstract: PROBLEM TO BE SOLVED: To attain an optimal characteristic when performing recording to a write-once optical disk using blue-violet laser. SOLUTION: An optical disk recording and reproducing device 10 is provided with an LD control part 17 for controlling emitting power of laser at the time of writing data. If a channel clock period is T, the LD control part 17 emits pulse light of n/2 times (round down decimals) when forming a recording mark of a length of n x T (n ; an integer of 2 or larger). When forming an even-number times recording mark of 6T or longer, each intermediate pulse light except the head pulse and the last pulse among the n/2 time pulse light is emitted with the phase synchronized with the channel clock. When forming an odd-number times recording mark of 6T or longer, the intermediate is emitted with a delay from the synchronized phase by T/2. COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To prevent the wavelength of a laser beam from instantaneously changed in response to a drive current pulse supplied in a semiconductor laser. SOLUTION: First, as a semiconductor laser apparatus, a first region formed with a first laser unit is thermally coupled to a second region formed with a second laser unit or a resistor so that heat generated in one region is transmitted to the other region. A method for driving this semiconductor laser apparatus includes a step of supplying currents to the first region and the second region by different pulses so as to make the sum of heating quantities in the first region and the second region constant. Thus, the sum of the heating quantities of the first region and the second region becomes constant. As a result the heat generated in one region is transmitted to the other region, and hence temperatures of the first region and the second region can be made constant. COPYRIGHT: (C)2004,JPO&NCIPI

Abstract: PROBLEM TO BE SOLVED: To provide an optical recording medium for a near field system which has high intensity of reproduced signals and which is hardly damaged on the surface, and to provide a production method of the medium and an optical recording device equipped with that optical recording medium. SOLUTION: The optical recording medium consists of a substrate 11, reflection film 12 formed on the substrate 11, recording layer 14 formed on the reflection film 12, and first protective layer 15 formed on the recording layer 14, and information is recorded and reproduced by irradiating the recording layer 14 with light from an optical system through the first protective layer 15 side. An antireflection multilayered film 19 which causes no reflection of light on the surface of the first protective layer 15 is formed on first protective layer 15. The gap between the antireflection multilayered film 19 and the optical system forms a near field, and the antireflection multilayered film 19 is a multilayered film consisting of layers having a specified refractive index and film thickness to mitigate changes in the reproducing signal intensity caused by changes in the gap. The invention also provides the production method of the medium and an optical recording device having that optical recording medium.
