摘要： A method of manufacturing a magnetic recording medium, comprises steps of providing a non-magnetic substrate for a magnetic medium, the substrate including at least one major surface having a contact start/stop (CSS) or landing zone and a data zone; and forming a pattern of recesses in the substrate surface in said CSS or landing zone by embossing utilizing a stamper having a surface including a negative image pattern of said pattern of recesses. Embodiments of the invention include magnetic media comprising a non-magnetic substrate including at least one major surface having a contact start/stop (CSS) or landing zone and a data zone, said substrate surface in said CSS or landing zone comprising an embossed pattern of recesses. In addition, the data zone of the substrate surface may include an embossed servo pattern formed simultaneously with the embossed pattern of recesses formed in the landing zone.

摘要： An apparatus and method for impact response testing of materials such as magnetic discs of a disc drive. The apparatus of the present invention supports a target disc in cooperative relationship with a sub-millimeter impact test ball such that the test ball can be dropped on selected portions of the target disc from selected heights above the target disc. The apparatus permits the method of observing the characteristics of a detent made in the target disc, by use of a high resolution surface profiler, and interpolating the observed characteristics to analytical standards which, for a given test ball size and drop height, indicate the dynamic hardness of the target disc at that test location. A vacuum is used to support the test ball above the disc, and a vacuum release valve is provided to negate the vacuum and release the test ball.
