Abstract: The present invention provides methods and apparatus for stabilizing data storage media during laser servowriting of optical servo tracks on the media. The apparatus includes a spindle for rotating the media during servowriting, a fixed media platform, and a media support for stabilizing the vertical position of the media during servowriting. The media support may include channels to reduce or control the formation of an air bearing in the area of servowriting to stabilize the vertical positioning of the media. The media support may also include a vacuum slot for drawing a vacuum through the channels.

Abstract: Methods and apparatus for providing Bernoulli stabilization to flexible media in an information storage system, are shown to include a stabilizer having a body on which a first surface is formed of a contour sufficient to provide Bernoulli stabilization to media passing thereover. The stabilizer is positioned so that the first surface is proximate backside of the media. In one embodiment, the first surface has a number of grooves which channel air passing between the first surface and the backside. In those situations where the flexible media includes two flexible disks, each having an active side and a backside and where the disks are oriented so that the backsides face one another, the body further includes a second surface of a contour sufficient to provide Bernoulli stabilization to media passing thereover. In such situations the stabilizer is positioned between the disks.
