Abstract
A magazine storage system for storing and retrieving recording strips. The system includes a magazine, having shelves for storing the strips, and a loop-shaped drive. The strips are transported between the magazine and the drive by conduits having air jets emanating from holes therein. The system provides rapid access to large amounts of stored information.
Claims19
A magazine storage system for recording strips, comprising:
- a loop-shaped drive comprising a first loop-shaped conduit having an inner periphery and an outer periphery, the first conduit having a first continuous working surface on an exterior surface of one of the peripheries, the first working surface having a first plurality of orifices for directing fluid, supplied to the first conduit, to support and transport the strip around said one of the peripheries in at least a first direction and into close proximity with at least one transducer;
- a magazine comprising a plurality of shelves for storing recording strips thereon;
- a second conduit having a second continuous working surface, the second working surface having a second plurality of orifices for directing fluid, supplied to the second conduit, to support a recording strip and transport it from the magazine to the drive, wherein the orifices are provided on both sides of a longitudinal centerline along a direction of travel of the strip;
- a third conduit having a third continuous working surface, the third working surface having a third plurality of orifices for directing fluid, supplied to the third conduit, to support a recording strip and transport it from the drive to the magazine, wherein the orifices are provided on both sides of a longitudinal centerline along a direction of travel of the strip;
- and
- a cusp for facilitating transport of a recording strip from the shelves to the second working surface, wherein the cusp can be moved among the shelves, whereby any desired recording strip in the magazine may be accessed, and wherein the recording strip is transported, by fluid streams originating from the shelves, from the shelves via the cusp to the second working surface.

A magazine storage system for reading/writing both sides of a recording strip comprising:
- a first loop-shaped drive comprising a first loop-shaped conduit having an inner periphery and an outer periphery, the first conduit having a first continuous working surface on an exterior surface of one of the peripheries, the first working surface having a first plurality of orifices for directing fluid, supplied to the first conduit, to support and transport the strip around said one of the peripheries in at least a first direction and into close proximity with at least one transducer, and wherein the strip has first and second major surfaces, whereby the first major surface of the strip may be read/written by the first drive;
- a second loop-shaped drive comprising a second conduit which is loop-shaped and has an inner periphery and an outer periphery, the second conduit having a second continuous working surface on an exterior surface of one of the peripheries, the second working surface having a second plurality of orifices for directing fluid, supplied to the second conduit, to support and transport the strip around said one of the peripheries in at least a first direction and into close proximity with a second transducer, whereby the second major surface of the strip may be read/written by the second drive;
- a magazine comprising a plurality of shelves for storing recording strips thereon;
- a third conduit having a third working surface having a third plurality of orifices for directing fluid, supplied to the third conduit, to support a recording strip and transport it between the magazine and the drives;
- means for manipulating a recording strip so that the first drive may read/write the first major surface of the strip and the second drive may read/write the second major surface of the strip, whereby the system may read/write both surfaces of the strip;
- and
- a cusp for facilitating transport of a recording strip from the shelves to the third working surface, wherein the cusp can be moved among the shelves, whereby any desired recording strip in the magazine may be accessed, and wherein the recording strip is transported, by fluid streams originating from the shelves, from the shelves via the cusp to the third working surface.
