摘要： A guard device for a grinding wheel in a grinding machine comprises a side guard plate pivotably mounted upon a guard body for covering one side face of the grinding wheel. A front cover member is slidably mounted upon the top portion of the guard body for covering the upper front portion of the grinding wheel. A latch member is mounted on the front cover member to be engaged with a saw-toothed member so as to restrict movement of the front cover member away from the periphery of the grinding wheel but to allow movement of the front cover member toward the periphery of the grinding wheel. A locking member is pivotably mounted on the top of the guard body to lock the side guard plate in a closed state. When the locking member is pivoted to be disengaged from the side guard plate, the saw-toothed member is also disengaged from the latch member.

摘要： A magneto-optical recording medium and a method for recording and reproduction thereon are provided in order to reproduce information recorded by multi-valued recording at a high S/N ratio. Disclosed is a magneto-optical recording medium including two magnetic layers capable of four-valued recording based on four combined magnetization states. Magnitudes of reproduction signals concerning the four magnetization states, obtained upon reproduction at a wavelength λ1, are different from those obtained upon reproduction at a wavelength λ2. The two magnetic layers, on which a signal (a) is recorded, are irradiated with light beams having the wavelengths λ1 and λ2 respectively. Signals (d), (e) reproduced from respective reflected light beams are sliced by using at least one slice level to obtain two-valued or higher multi-valued reproduction signals respectively. The two-valued or higher multi-valued reproduction signals (f), (g) from the respective wavelengths are mutually subjected to logical operation to reproduce recorded information (i).

摘要： A magnetic recording medium comprises an information-recording film and a ferromagnetic film on a substrate. The information-recording film is composed of, for example, an amorphous ferrimagnetic material having perpendicular magnetization. Further, the ferromagnetic film is composed of a magnetic material which has saturation magnetization larger than that of the information-recording film. Accordingly, the leak magnetic flux from the ferromagnetic film is larger than that from the information-recording film. The magnetic recording medium and a magnetic recording apparatus are obtained, which are excellent in thermal stability and which are preferred to perform super high density recording.

摘要： External magnetic fields H(x) or reproducing light beams L(x) having different intensity patterns are applied to an identical recording position on a magneto-optical recording medium so that different pieces of information corresponding to the patterns are reproduced from the identical recording position. A function H(x) or L(x) is a password for obtaining the information. Only a person, who knows the function, can access specified information recorded on the magneto-optical recording medium. The function H(x) or L(x) is a function in which the magnetic field intensity or the light intensity is modulated with respect to the recording position x so that magnetic domains may be thinned out to perform reproduction at a specified cycle from continuous magnetic domains in a recording area. Other than the use for the purpose of security, reproduced C/N can be remarkably improved by performing reproduction n times while radiating a reproducing light beam PL/PH which is power-modulated so that the high power PH is applied at every cycle which is not less than n times the recording clock, to a specified magneto-optical recording medium capable of magnetic domain-magnifying reproduction.

摘要： A magneto-optical disk apparatus and an adjustment method of a head mechanism are provided for strictly and quickly adjusting a setting position of a magnetic head with respect to an optical axis of an optical head. The adjustment method is executed by the following steps. A magnetic super resolution type magneto-optical disk is mounted to the magneto-optical disk apparatus provided with the optical head and the magnetic head. Then, an external magnetic field from the magnetic head is applied onto the magneto-optical disk as applying a laser beam of a reproduction level onto the magneto-optical disk. Then, a reproduction signal output read from the magneto-optical disk is detected concurrently with the application of the external magnetic field. Next, a fine adjustment mechanism is operated so that the reproduction signal output is made maximum with respect to the direction of the external magnetic field, for the purpose of sequentially changing a setting position of the magnetic head with respect of the optical axis of the optical head.

摘要： A magneto-optical recording medium comprises, on a substrate, a dielectric layer, a GdFeCo reproducing layer, a non-magnetic layer, and a TbFeCo recording layer. Upon reproduction, a DC magnetic field Hex is applied in the recording direction, and a reproducing light beam is radiated while being modulated to have a low power and a high power in synchronization with a reproducing clock.

摘要： A magneto-optical recording medium comprises in combination: a magneto-optical recording layer capable of writing or erasing information by a laser beam and an external magnetic field and of reading the information by a Kerr effect; and a substrate having the magneto-optical recording layer formed thereon. The magneto-optical recording layer has at least two layers, including a first magneto-optical recording layer and a second magneto-optical recording layer which are magnetically coupled together. The first magneto-optical recording layer is a layer providing a greater magneto-optical effect in a short light wavelength range than the second magneto-optical recording layer though that having less perpendicular magnetic energy than this, as is provided on an irradiation side of the laser beam. It provides advantages in both the magneto-optical effect and perpendicular anisotropy in consideration of the thicknesses or compositions of the first and second magneto-optical recording layers.
