摘要： The magnetic disk contains on a disk substrate a magnetic layer comprising a binder, magnetic particles and abrasion-resistant particles, the abrasion-resistant particles being enveloped with a layer intensifying the bond between binder and abrasion-resistant particles. The enveloping layer either has a large specific surface and consists e.g. of SiO.sub.2 /Al.sub.2 O.sub.3 produced by processing the particles with an alkali metal silicate solution and an aluminum sulphate solution, or it is chemically bonded to the binder by enveloping the particles with poly(tetrafluroethylene) and coupling the latter, via an amino bridge to the binder, e.g. an epoxide resin.The magnetic disk according to the invention minimizes the abrasion of the magnetic layer as well as the damaging of the magnetic layer and of the magnetic head by knocked-out abrasion-resistant particles.

摘要： A method and apparatus is provided for characterizing magnetic coating compositions that contain magnetic particles dispersed in a solvent resin matrix. The coating composition, as it passes through a tube, is subjected to an alternating magnetic field and perpendicular thereto a constant magnetic field of appropriate field strength and duration. Via a measuring coil surrounding the tube the induced signal in the composition is monitored and the degree of dispersion, is measured by measuring the magnetic susceptibility of the coating material. By applying a constant magnetic field the degree of dispersion cna be changed at least for a certain time. The method and apparatus of the present invention can be incorporated into a coating apparatus to monitor and improve the magnetic characteristics of the coating material being applied to a substrate.

摘要： An optical storage disk includes a glass substrate (1) into which guide tracks (3) for servo-controlling the focussed light beams are directly stamped in by hot stamp process. After stamping, the glass substrate is thermally quenched in the stamping device to increase its breaking resistance through thermal curing. In order to achieve uniform guide tracks over the entire surface of an optical storage disk, flexible stamp stencils (35) in a flexible holder (34) are used whose curvature can be changed by applying hydro-static pressure. Suitable stamp stencils include monocristalline silicon disks with surface hardening, or of metal disks, structured photolithographic processes. The stamp lands are made with bevelled edges to facilitate the separating of stamp and glass substrate after cooling.

摘要： For characterizing coating compositions with magnetic particles the coating composition is subjected to an alternating magnetic field of variable frequency. The field induced by the coating composition after energization is recorded, and thus the susceptibility of the coating composition is measured. Depending on the variable frequency, conclusions can be made regarding the degree of dispersion, particle density, and viscosity of the coating composition. The variable frequency is between 1 and 100 cps, and the field intensity of the energizing field should be lower than 10 Oerstedt. The coating composition is fluid or stagnant in a pipe *1, 11 which is surrounded by field coil and measuring coil.

摘要： Multi-layer magnetic thin film disks comprising a synthetic resin layer on an aluminum-containing substrate and an overlying metallic magnetic layer, are liable to have pin holes in the synthetic resin layer caused by galvanic corrosion of the aluminum in the substrate. The pin holes are passivated by aluminum oxide produced therein by anodically oxidizing the aluminum of the substrate in an electrolytic bath, the electric voltage of which is well below the normal passivation voltage for aluminum.

摘要： Direct method for measuring the magnetostriction constant .lambda..sub.s of soft magnetic and isotropic magnetic materials. A thin film sample is cantilevered and clamped at one edge. Under the influence of a magnetic AC field and the magnetostriction effect of the sample material, the free end of the cantilevered sample is deflected and oscillates with twice the frequency of the AC field. The resonance amplitude a.sub.res is measured by using a laser beam impinging upon the oscillating sample and measuring the reflected beam amplitude by means of a position-sensitive photodiode. The AC output signal of the photodiode is proportional to the sample amplitude. The magnetostriction constant .lambda..sub.s is directly proportional to the resonance amplitude a.sub.res multiplied by a constant factor which depends on known geometry and properties of the sample material.

摘要： A record carrier for a magnetic thin film metal layer includes a substrate coated with a pigmented epoxy resin as a synthetic substance layer. The pigment includes approximately 20% titanium dioxide and approximately 2% aluminum oxide. A thin getter metal layer is deposited over the synthetic substance layer for absorbing the outgasing from the synthetic substance layer. A relatively thicker metal layer such as chromium is then deposited over the getter layer for enhancing the magnetic properties of the subsequently deposited magnetic layer.

摘要： For a metallic thin film magnetic disk, a chromium undercoat and a magnetic layer, in particular of an FeCoCr alloy, are obliquely sputtered by means of a sputtering system onto a substrate at an angle of incidence of about 60.degree.. The operating pressure of the argon gas atmosphere is between 5 and 15 .mu.bar and the thickness (t.sub.Cr) of the undercoat, which also influences the coercive field strength, is between about 50 and 180 nm. By means of a sector shutter of suitable shape, the thickness distribution between the inner diameter ID and the outer diameter OD of the storage area of the magnetic disk can be influenced in the desired manner.
