Title:
METHOD OF PHOTOGRAPHICALLY RECORDING DIGITAL SPEECH BITS AND ITS DEVICE, AND PHOTOSENSITIVE MEDIUM AND PRINT GENERATION DEVICE
Document Type and Number:
Japanese Patent JPH0660376
Kind Code:
A
Abstract:
PURPOSE: To obtain a method of recording multi-channel digital speech information on a continuously moving video film with an extremely high resolution.
CONSTITUTION: Each digital sound track is recorded in a bit area array arranged in order of horizontal and vertical rows. Each horizontal row of digital audio bits is simultaneously recorded by exposing a film to radiation modulated by a straight shutter array. The radiation transmitted by each shutter array is projected on a horizontal row of the spot. A width of each spot 30A extends to a whole one bit area 30', but a length extends to only a part of the area 30'.
