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.

A guidance system for tape in a tape cartridge includes two corner guides and an optional third guide. The two corner guides may be angled or tapered to produce a bow or slope in the tape, and to steer the tape. If provided, the third guide is readily adjustable during manufacture to an exact predetermined distance from the two corner guides, thereby avoiding problems due to build-up of manufacturing tolerances. A method of constructing such a system provides an interference fit ferrule on a pin or a nail-like pin as the third guide, such that the position of the ferrule or nail head of the pin can be adjusted to the exact position desired during manufacture.
