A slider head assembly for flying a magnetic head at very low clearances on a fluid film over a moving recording media. This improved slider head assembly has at least one air bearing surface that flies above the recording medium due to pressurization of air under that bearing surface as the recording medium is rotated. The air bearing surface is provided with a transverse pressurization contour (TPC) along each side edge of the bearing surface such that any air flow from the side of the slider assembly, due to skew angle operation and/or access velocity, produces pressurization adjacent to one side edge and expansion adjacent to the other side edge of each air bearing surface. The pressure distribution across each air bearing surface is substantially symmetrical from side to side. This construction makes the slider assembly flying height and roll angle essentially insensitive to skew angle and/or access velocity. One of the embodiments utilizes a TPC having a linear taper of generally less than one degree.

A metal foil disk offers some of the best characteristics of both the hard disk and floppy disk for digital data storage. One embodiment uses an opposed slider air bearing arrangement that provides advantages when used with a high speed metal foil disk in either a fixed or removable format. Use is made of the fact that the opposing sliders interact through their influence on the flexible disk that is sandwiched between them. Asymmetry of opposing air bearings may be created by etching the air bearing pad opposite the recording element pad to a depth sufficient that the flying height and air film stiffness of the opposing pad reach desired levels. The result is an air bearing interface with low flying height and high stiffness over the recording element opposed by a high flying height and low stiffness on the other side of the disk. This air bearing interface provides an enhanced dynamic flexibility to the metal foil disk when it is subjected to mechanical shock. As a result, the opposed slider arrangement with metal foil disk is able to avoid contact and impact when subjected to substantial levels of mechanical shock.

A slider assembly for supporting a recording element in operative relation to a flexible moving recording medium is disclosed. The slider may have a face including air bearing surfaces positioned toward the recording medium. A recording element may be in an air bearing surface near the trailing edge of the face, wherein there is no other slider or other supporting surface on an opposite side of the recording medium. A vacuum cavity may be formed in the face for creation of sub-ambient pressure to attract the slider toward the recording medium. An air bearing surface may be provided with a transverse pressure contour (TPC) along at least one of its edges for providing flying height control, with the TPC having a step geometry. A mounting device may mount the slider in a biased manner toward the recording medium and urge the slider toward the recording medium.

A data storage device uses a foil disk platter with significantly reduced inertia and weight as compared to the thick aluminum or glass disk platter in a typical hard disk drive. The reduced rotating inertia of the foil disk enables faster spin-up performance which can be used to reduce decrease the power consumed by the unit. In portable appliances that use disk drive storage devices battery life can be extended significantly and the unit can be made thinner and lighter. Certain parameters of the foil disk substrate may be determined, to provide improved control of disk flutter, from a range parameter defined by.
