摘要： A data storage device includes optical media or magneto-optic media. Formed on the optical or magneto-optic media is an amorphous or a substantially amorphous ZrO2 layer (102; 204). The ZrO2 layer is typically formed by sputtering, and includes an additive which renders the ZrO2 either amorphous or substantially amorphous. Because of the amorphous or near amorphous nature of the ZrO2 film (102, 204), noise is not introduced into a laser beam signal passing therethrough by crystal grain boundaries in the film (102, 204). In addition, because the film (102, 204) is substantially amorphous, birefringence will not generate noise in the laser passing therethrough caused by polymorphism in the film (102, 204).

摘要： A carrier plate (15) has essentially circular openings (11) for receipt of smaller diameter circular magnetic memory disks (20). Each disk has a plugged aperture, a planar annular band (23) on each side for receiving magnetic media (8), an outer peripheral edge (24) and a chamfer (22) therebetween. An integral stump segment (30) and a pair of integral U-shape channel retainers (40) extend from plate opening (11) to a position overlapping disk chamfer (22) to prevent a disk resting vertically on the stump segment (30) from falling out of the plate (15). Vertical holding walls (40) extend integrally and downwardly from a rear leg of the channel to insure vertical orientation of the disk (20) and stop walls (50) extend integrally and upwardly from that rear leg to prevent overtilting of the disk during its insertion into the plate (15). Gaps (31, 32, 33) are provided between the disk peripheral edge (24) and the opening (11) over about 248° allowing magnetic media to effectively coat the entire annular band surfaces (23).

摘要： A carbon film for protecting a magnetic disk is sputtered in the presence of hydrogen. If a sufficient amount of hydrogen is present in the sputtering chamber (5), the resulting carbon film will exhibit superior mechanical characteristics, i.e. an enhanced wear resistance during a contact-start-stop or drag test in a disk drive. Sputtering in the presence of hydrogen can be accomplished by either DC or RF magnetron sputtering, or DC or RF diode sputtering.

摘要： A robotic method is disclosed for connectively inserting a plug into a central aperture on a blank disk, moving the plugged disk to a panel which is conveyed to a position for coating a magnetic material on series of mountes disks, demounting the disks from the panel, removing the plug from the each processed disk and returing the plug for reinsertion into a subsequent blank disk. The robotic system includes a series of cassettes (55, 56) holding blank disks which are ejected in seriatim from each cassette and plugged by manipulation of robotic arms at that cassette position. Each disk is transported by a robotic arm and inserted into a series of disk-holding apertures (11) in a carrier panel (10) and, after processing of multiple disks in the panel, the processed disks are removed from the carrier panel by the robotic arm to a second cassette position where the plugs (20) are removed from the processed disk and the plugs conveyed by a pair of robotic arms (40, 41) or by the robotic arm (50) acting in conjunction with an auxiliary robotic arm for reinsertion into other blank disks. Sensor means are provided for accurately positioning the robotic arm with respect to the position of the carrier panel to be loaded. The robotic arms may be programmed to tilt the grasped disk and plug with respect to the carrier panel to facilitate insertion or removal of the disks into the carrier panel.

摘要： 57 A carrier is provided to hold a disk while magnetic material is plated simultaneously on the two surfaces of the disk. The carrier contains a first opening substantially the same diameter as the disk and a second opening formed about a center line offset from the center line of the first opening so as to form a recess around a portion of the edge of the first opening. The recess allows the disk to be mounted into the carrier by placing the disk in a portion of the first opening and in a portion of the recess without having the surface of the disk touching the surface of the recess. The disk is then lowered into the first opening while leaving the remainder of the carrier material adjacent the recess to block the flow of plasma and impurities from one side of the disk to the other during the coating of the surfaces of the disk with magnetic media. A plug is provided for placement in the center hole of the disk. The plug is in two portions, one of which contains a spring means for flexibly holding the two halves together during the coating of the disk with magnetic media so that thermal expansion of the disk during coating does not result in the plug rattling or coming loose from the disk. The plug also serves as a knob or handle by which the disk can be handled, carrier or mounted. A plurality of openings are provided in one carrier to allow both surfaces of a corresponding plurality of disks to be coated simul- i taneousty with magnetic media.

摘要： A new magnetic alloy exhibits high Hc and Ms while exhibiting excellent corrosion resistance, thereby providing ideal physical properties for high density recording applications. Other parameters of the media, such as SNR, PW50 and S are at least maintained, if not also improved. The alloy contains cobalt and up to 10 at.% Ni, up to 20 at.% Pt, up to 10 at.%Ta, up to 10 at.% Ti, and optionally up to 6 at.% B. The ratio of the tantalum to titanium in the alloy is between 3:1 and 1:3. The alloy is deposited by vacuum deposition (typically sputtering) on a similarly deposited non-magnetic Ni alloy under layer. Nitrogen and/or oxygen may be introduced into the alloy during deposition to improve SNR. Other corrosion-resistant thin film alloys may also be obtained by the inclusion of Ta and Ti.
