Abstract: PROBLEM TO BE SOLVED: To obtain a regenerative signal with less jitters and to improve linear density by applying a fixed directional magnetic field to a recording medium, detecting an edge of a side that movement of a magnetic wall is promoted by applying the magnetic field between a front edge and a rear edge of a magnetic domain and reproducing information.

Thus, a fixed intensity reproducing beam is emitted from an optical head 5 to a target track on a magneto-optical disk 1, and a fixed magnetic field is applied from the magnetic head 6, and a detection signal is obtained from an optical head 5. A position. traversing a slice level is found from the detection signal by an information reproducing circuit 9, and an edge detection signal is generated. By masking an edge signal with the position of the rising of the detection signal, the position of the front edge of an arrow feather shaped magnetic domain is detected, and a magnetic wall movement regenerative signal is generated.

IPC: G02B26/10
Filed: 1984-12-03
Abstract: PURPOSE:To eliminate rereflection and to equalize longitudinal and lateral diameters of a beam spot by providing a half mirror, which has a reflecting surface inclined to a plane orthogonal to the optical axis vertical to a photosensitive surface, between a moving mirror and a photosensitive body. CONSTITUTION:A half mirror 27 where a reflecting surface 28 is formed on the side of a photosensitive body 6 is provided on the optical axis of scanning between a moving mirror 24 and the photosensitive body 6. The reflecting surface 28 is inclined to a plane orthogonal to an optical axis 29 vertical to a photosensitive surface 6a. Consequently, though a part of the beam irradiated to the photosensitive body 6 is reflected and reaches the reflecting surface 28, it is reflected to the outside of the optical aixs. Thus, a conventional defect that the spot diameter of the beam is long in the peripheral direction of the photosensitive body and is short in the axial direction by rereflection is eliminated to equalize longitudinal and lateral diameters of the spot.

Title: Tracking servo device
Inventor: SAKATA HARUYASU
IPC: G11B7/09
Filed: 1988-10-11
Abstract: PURPOSE:To perform stable jump operation by changing equalizer characteristic or a gain at the time of detecting that the variation per a unit time of the level of the tracking error signal, which is obtained by passing of an information reading spot on a recording track at the time of convergence for servo leading-in after generation of a decelerating pulse, is larger than a reference value. CONSTITUTION:An inclination detecting circuit 13 detects the variation of levels of tracking error signals S2 and S3, which are obtained at the time when the information reading spot passes a middle position on the recording track, to output inclination information corresponding to its inclination. This information is compared with a prescribed threshold (reference value) by a threshold comparing circuit 14. When it is larger than the inclination threshold, the threshold comparing circuit 14 changes the equalizer characteristic or the gain for a prescribed time after this detection. Thus, the jump operation is stabilized.

IPC: G01N3/32
Filed: 1992-09-25
Abstract: PURPOSE:To evaluate a crack propagation speed, etc., by using a stress enlarging coefficient value by applying a compression load to a testpiece which has a rectangular parallelepiped shape and in which a length is larger than a width and a precrack is formed at the center. CONSTITUTION:A compression load is applied to two crossing lines of a surface parallel to a testing section and an end face of a precrack side at an interval I=W/2+2e to be eccentrically deviated outside from a center of the testing section and both side faces by using a testpiece 1 in which a precrack 2 is formed. When a composite force balanced with the compression load is loaded with the compression load P at the other end face opposite to the precrack, a stress enlarging coefficient K1 occurs only in a mode one component at an end of the precrack on the testing section, and the crack can be propagated along it. A stable crack growing area in which sufficiently wide L-W in which a K value is decided only by the load irrespective of the length of the crack is obtained under a load control. When a hysteresis is measured and a compliance of its linear range is obtained, a crack propagation amount can be immediately obtained.
