Abstract: The current invention provides an apparatus and method of collecting waste materials produced during laser etching of a floptical medium (1) without blocking access to the medium surface. The invention also improves collection efficiency by applying a uniform low-pressure air around the outer edge of the medium (1). Because the air pressure is applied around the edge, there is no necessity to coordinate a movement or timing of the current invention with respect to the laser etching unit (2).

Abstract: The intensity of a beam of light used to etch concentric servo tracks (12) on a magnetic medium is adjusted with an acousto-optical device to maintain the energy density delivered by the beam substantially constant while the optics (71) which generate the beam move radially of the disk (61).

Abstract: A magnetic tape drive for driving magnetic tape (14) in a cartridge (10) of the type in which a driven roller (12) in an exposed edge of the cartridge (10) moves the tape past a read/write head (16) in the drive. A drive roller (18) in the drive is rotated by a motor (22). The drive roller engages an idler capstan (20) which, in turn, engages the driven roller (12) in the cartridge (10).

Abstract: A method and device are provided for inexpensively and easily masking a magnetic recording head to be ion-beam milled. According to the invention, a magnetic mask (36) comprising a magnet shaped to form a mask (36) for a predefined pattern, is used in place of more expensive and complex photolithographic techniques to mask, or protect, a predefined area of the magnetic recording head being milled from the ion-beam.
