    Abstract: An image pickup device includes: a base board provided with an image sensor; an outer frame member fixed on the base board for shielding at least the image sensor; an optical member having a lens portion that forms an image of an object on a light-receiving surface of the image sensor and an outer form that supports the lens portion and is fitted in the outer frame member; a pressing member for urging the optical member in a direction of an optical axis of the lens portion with prescribed pressing force, to bring the optical member into contact with the base board or with the image sensor; and a rotation-preventing mechanism provided on an interfitting part where the optical member is fitted in the outer frame member for preventing rotation of the optical member around the optical axis.

    Abstract: 5 3 MAGNETIC RECORDING MEDIUM SUBSTRATE AND MANUFACTURING METHOD THEREOF, AND MAGNETIC RECORDING MEDIUM AND MANUFACTURING METHOD THEREOF ABSTRACT 5 PROVIDED IS A MAGNETIC RECORDING MEDIUM SUBSTRATE SUITABLE FOR PREPARATION OF A DT MEDIUM AND A PATTERNED MEDIUM, AND THE MAGNETIC RECORDING MEDIUM SUBSTRATE IS POSSIBLE TO HE OF EASY PREPARATION OF THE DT MEDIUM AND THE PATTERNED MEDIUM WITH NO COMPLICATED PROCESSES. DISCLOSED IS 10 A MAGNETIC RECORDING MEDIUM SUBSTRATE COMPRISING A CIRCULAR PLATE-SHAPED SUBSTRATE MADE OF A NONMAGNETIC BASE MATERIAL, WHEREIN A PREDETERMINED REGION OF A SURFACE OF THE SUBSTRATE TO FORM A MAGNETIC FILM ON THE SURFACE IS MORE ROUGHENED THAN ANOTHER REGION OF THE SURFACE. WHEN FORMING A MAGNETIC FILM 15 ON THIS SUBSTRATE, THE MAGNETIC FILM IS FORMED IN THE REGION OF THE SUBSTRATE SURFACE, WHICH IS MORE ROUGHENED THAN THE OTHER REGION, TO EASILY PREPARE THE DT MEDIUM AND THE PATTERNED MEDIUM.

    Inventor: NOGUCHI KAZUTAKA

    Abstract: The present invention provides an objective lens for optical pick-up devices in which the amount of change in the astigmatic aberration is small when there is a temperature distribution that is not circularly symmetric with respect to the optical axis within an objective lens constructed with at least two optical elements and which permits stable and high-speed information recording and reproduction with high-density optical disks, and to provide further an optical pick-up device provided with such an objective lens, and an optical information recording and/or reproducing apparatus employing such an optical pick-up device.

    Inventor: YAMAGUCHI SUSUMU

    Abstract: An image pickup lens has four lenses arranged in an order of a first lens, a second lens, a third lens and a fourth lens from an object side. The first lens has positive refractive power and has a convex surface facing toward an object side, the second lens has the positive refractive power, the third lens has negative refractive power and has a concave surface facing toward the object side to be formed in a meniscus shape, and the fourth lens has the positive or negative refractive power and has a convex surface facing toward the object side to be formed in the meniscus shape. An image pickup unit (50) comprising a solid state pickup element (51), a substrate (52) for holding the solid state image pickup element, a casing (53) and the image pickup lens (L1-L4) has a length of not more than 15 mm.
