In one embodiment, a substantially amorphous grain boundary layer of a magnetic recording layer made of CoCrPt alloy and Si oxide contains a ferromagnetic element in a concentration from about 30 at. % to 50 at. % or more preferably from about 35 at. % to 47 at. %, so that intergrain exchange interaction takes place moderately. As a consequence, SNR of 18 dB or more and thermal stability of 3%/decade or less are achieved.

摘要： Disclosed is a magnetic recording medium and a method for manufacturing the same to provide a magnetic recording medium reducing medium noise and having excellent thermal stability. The magnetic recording medium includes a substantially amorphous seed layer and a polycrystal underlayer made of crystal grains having a substantially columnar structure, the polycrystal underlayer contacting thereto. In a boundary between the seed layer and the underlayer, fine grooves having a period up to as large as the magnetic layer crystal grain diameter are formed in the disc circumferential direction. Accordingly, the magnetic recording medium is allowed to have a grain shape with a value obtained by dividing the average grain diameter for the disc circumferential direction by the average grain diameter for the disc radial direction of no less than 0.5 and no more than 0.9, thus achieving simultaneously reduction of the medium noise and thermal stability.

摘要： A collecting agency supplies a collecting agency name and a money bag number to a service providing terminal. In response to dealing requests from user terminals, the service providing terminal sends, to the user terminals, information which contains the collecting agency name (Id) and the money bag number (Gb) supplied from the collecting agency. The user terminals generate digital signatures containing the received request information, affix the generated signatures to electronic tickets to be used, and send the electronic tickets with the signatures to the service providing terminal. The service providing terminal, which has received the used electronic tickets, collects those electronic tickets which include the same money bag number supplied from the collecting agency into a group (a money bag), and sends the group of electronic tickets to the collecting agency.

摘要： The magnetic storage apparatus has a high reliability at a recording density of 2 gigabits or more per square inch. The longitudinal recording media necessary to realize the apparatus has a low media noise and is immune from the influence of thermal fluctuations. The magnetic storage apparatus has a longitudinal magnetic recording media including a magnetic layer which is formed on a substrate via a multi-layered underlayer; a driver for driving the recording media in a recording direction; a magnetic head including a recording section and a read-back section; a driver for moving the magnetic head relatively with respect to the longitudinal magnetic recording media; and a read/write signal processor for processing input signals to the magnetic head and output signal read-back therefrom. The read-back section of the magnetic head includes a magnetoresistive head. One layer of the multi-layered underlayer in the longitudinal magnetic recording media which is in contact with the magnetic layer has a substantially hexagonal close-packed (hcp) structure and has crystal grains whose c-axes are substantially parallel with the substrate plane.

摘要： An electron microscope for observing a magnetization state of a specimen with high resolution and an electron microscopic method. The electron microscope comprises an electron beam irradiating device including a scanning coil 3 and an objective lens 4 to irradiate an electron beam 2 emitted from an electron source 1 on a desired part of a specimen 51, and a circularly polarized light detector including a quarter wave plate 8, a polarizer 9 and a photodetector 11 to detect circularly polarized light generated from the electron beam irradiated part of the specimen 51. Since the intensity of the circularly polarized light generated from the specimen irradiated with the electron beam depends on the direction of magnetization in the electron beam irradiated part and the detecting direction, the distribution of magnetization can be measured by observing a scanning image in the form of a luminance signal indicative of the intensity of the circularly polarized light while scanning the electron beam irradiated part on the surface of the specimen.

摘要： A charged particle beam is transmitted through a specimen for producing an irregular pattern as a first image. Further, a magnetic field to be measured is arranged in space where a charged particle beam is passed between the specimen and an image plane thereby to produce a second image having an irregular pattern as in the foregoing case. The first image and the second image are processed to produce the deflection angle of the charged particle beam due to the magnetic field. This deflection angle is extracted from the entire positions of a cross section of the space where measurement is desired, thereby constructing projection data of a magnetic field by a charged particle beam. Furthermore, the magnetic field to be measured is rotated and the above-mentioned processing is performed from each direction to construct projection data. The projection data thus obtained and the computer tomography technique are used to determine a magnetic field at each point in space.
