摘要： A magnetic disk media is physically preformatted to have a non-user data area providing any of a servo pattern, a gray code pattern and a timing line pattern. The non-user data area patterns are preformatted to have non-recordable regions with a radial width that is always less than the track pitch of the data area. In exemplary implementations, servo patterns, gray code patterns and timing line patterns are physically preformatted to have a recordable:non-recordable radial width ratio substantially equal to that of a user data area. In certain embodiments, non-magnetic or magnetically suppressed regions having cross-track dimension substantially equal to that of spaces between tracks in the user data area are consecutively offset in a cross-track direction from the discrete track recording pattern of the user data area.

摘要： Recording media press systems and methods of operating such press systems. Embodiments of a press system include a first and second die at least one of which is configured to be coupled to an embossing foil. A stopper may be used to space the embossing foil apart from a magnetic recording disk disposed within the press system by a predetermined gap when the die set is in a closed position. In an embodiment, a piston disposed within at least one of the first and second die is moved relative to the first and second die to press the embossing foil against the magnetic recording disk after the die set stopped in the closed position by the stopper.

摘要： A manufacturing cell for inspecting workpieces such as magnetic disk substrates comprises an input conveyor for providing workpieces to be tested, one or more testers for inspecting the workpieces, and three or more output receptacles for receiving tested workpieces. One or more robotic arms move the workpieces from the input conveyor to the tester and from the tester to one of the output receptacles depending upon the results of the test performed by the tester. The output receptacles include a pass receptacle, a reject receptacle, and at least an additional receptacle for workpieces that are to be re-worked or studied further. If the additional receptacle is full, workpieces that would otherwise be provided to the additional bin are placed in the reject receptacle. The reject receptacle is very large, so that it is rarely filled to capacity, and it is rarely necessary to shut down the manufacturing cell to replace the reject receptacle.
