Abstract

A recording laser beam is modulated by an acousto-optic modulator with input image signals. The modulated laser beam expanded by a lens system impinges upon a light beam deflector. The light beam deflector includes a plurality of mirror surfaces in the form of a polygonal pyramid. A plurality of photosensitive recording media are supported on the inner surface of a cylindrical support member. The light beam deflector is located within the cylindrical support member for rotation about and sliding movement along the longitudinal axis of the cylindrical support member. The modulated and expanded laser beam impinges upon the light beam deflector at the apex of the polygonal pyramid at an angle parallel to the axis of the pyramid and divided into a plurality of light beams outwardly reflected by the mirror surfaces in a plurality of radial directions. The reflected light beams are focussed on the respective photosensitive recording media on the inner surface of the cylindrical support member. The reflected light beams are caused to scan the plurality of photosensitive recording media by rotating the light beam deflector and by axially moving the light beam deflector. Thus, the input image signals are simultaneously recorded on a plurality of photosensitive recording media.

Claims

1. A recording device for simultaneously recording input image signals on a plurality of photosensitive recording media comprising a substantially cylindrical support member on the inner surface of which the photosensitive recording media are supported, a plurality of mirror surfaces in the form of inclined surfaces of a polygonal pyramid provided within the support member, an acousto-optic modulator for modulating a recording light beam with the input image signals, and a means for guiding the modulated light beam along the longitudinal axis of the cylindrical support member, the central axis of the polygonal pyramid being in coincidence with the longitudinal axis of the cylindrical support member, the mirror surfaces being rotatable about the longitudinal axis of the cylindrical support member with respect thereto, the modulated light beam impinging upon the mirror surfaces at an area including the apex thereof travelling along the longitudinal axis of the cylindrical support member, the mirror surfaces reflecting the corresponding parts of the modulated light beam in different direction dividing the modulated light beam into a plurality of light beams, the divided light beams being focussed on the respective photosensitive recording media scanning the same by rotation about and sliding movement along the longitudinal axis of the cylindrical support member of the mirror surfaces thereby recording the input image signals on the photosensitive recording media.

2. A recording device as defined in claim 1 in which said mirror surfaces are plane mirror which are inclined with respect to the longitudinal axis of the support member by a predetermined angle.

3. A recording device as defined in claim 1 in which the mirror surfaces are concave mirrors and the modulated light beam is focussed on the surface of the photosensitive recording medium thereby.

4. A recording device as defined in claim 3 in which said concave mirrors are spherical concave mirrors.

5. A recording device as defined in claim 3 in which said concave mirrors are non-spherical mirrors.

6. A recording device as defined any one of in claims 3 to 5 in which the modulated light beam is collimated prior to impinging upon the concave mirrors.
