Abstract: There is disclosed a record media guide for optical scanners to position accurately the record media such as film during both the recording as well as the reading mode. The film guide provides a gaseous bearing to reduce film wear, prevents the deformation of film edge curl and allows for optical scanning without reflections.

Abstract: A wideband optical disc data record/playback apparatus is provided. The apparatus includes means for splitting the output of a single laser into multiple beams. The record beams are independently modulated and used to simultaneously record data at extremely high rates on the surface of an optical disc. The apparatus is capable of recording 1.times.10.sup.11 bits of data on one surface of an optical disc at data rates of 100 to 300 Mb/s. In addition, a plurality of coplanar low power beams are used for playback and data verification purposes. In the playback mode a single beam is split into a plurality of low power beams and one of the plurality of beams is dithered such that the dithered beam exhibits periodic excursions in a radial direction across the surface of the disc. The dithered beam is used for tracking purposes in both the playback and record mode. In a preferred embodiment the playback beams are split by an optical grating and dithered by an acousto-optic device.

Abstract: A photographic film recorder includes film-exposing apparatus having a laser light source for exposing the film, and a photographic film-developing apparatus. A film transport means transports the film at the same velocity through both the exposing apparatus and the developing apparatus, under control of a received film velocity signal. The time period each element of the film is in the developer varies inversely with film velocity. A plurality of transfer function look-up tables are provided for translating a received video density signal to a corresponding exposure signal for controlling the laser light source. Means responsive to the film velocity signal selects for use a transfer function look-up table which is appropriate for the time period each element of the film is in the developer.
