Abstract

A number of digitally encoded records (12) are loaded in a reproduction apparatus (13), such as a compact disc juke box. Covers (14) corresponding to the records (12) are photographically reduced in size. The photographically reduced covers are mounted on the reproduction apparatus so that the user can choose a particular record to be played by selecting the corresponding cover. In one example the covers (14) are arranged in a regular grid and the reproduction apparatus (13) is programmed with data correlating positions of covers in the grid with the corresponding records. The data may be provided in a programmable data cartridge (8). The grid (T) may have a touch-sensitive device (15,16) associated with it. Alternatively the user may use a numeric keypad to indicate the selected cover.

Claims

1. A method of controlling a musical reproduction unit for playing digitally encoded records, comprising assembling a plurality of digitally encoded records, photographically reducing covers of said records, loading said records in a musical reproduction unit arranged to play a selected one of said records in response to a choice made by a user, and mounting said photographically reduced covers on said unit in an array so that all covers for all records that are loaded in the unit are viewable at one time, whereby a user is enabled to choose a record by entering in said unit firstly an indication of a corresponding cover, and playing one of said records in response to a user selection made by touching a particular one of said covers.

2. The method of claim 1, wherein said digitally encoded records are compact discs.

3. The method of claim 2, wherein said covers are mounted on said reproduction unit in a regular array, the method further comprising programming said reproduction unit with data correlating positions of covers in said array and respective corresponding records, whereby said unit is responsive to an input from said user indicating a position of a cover to select a corresponding record for playing.

4. The method of claim 3, wherein said data correlating said position and said covers is provided in a programmable data cartridge, said method further comprising fitting said programmable data cartridge to said reproduction unit.

5. The method of claim 4, wherein title information for each compact disc is stored in said data storage cartridge, said method further comprising displaying title information for a chosen compact disc on visual display means.

6. A musical reproduction unit for playing digitally encoded records comprising a plurality of digitally encoded records loaded in the unit, the unit comprising:

photographically reduced covers of the records mounted on the unit in an array so that all covers for all said records that are loaded in said unit are viewable at one time;

a sensing means associated with at least one of said photographically reduced covers, said sensing means adapted to be activated by a user by touching a particular one of said covers and thereby selecting said particular cover; and

control means electrically connected with said sensing means, said control means adapted to operably play the record indicated by the selected cover when selected by a user.

7. The apparatus of claim 6, wherein said photographically reduced covers are mounted on said musical reproduction unit in a regular array, said control means is loaded with data correlating positions of covers in said regular array and respective corresponding records.

8. The apparatus of claim 7, wherein said control means include a programmable data cartridge fitted to said unit.

9. The musical reproduction unit of claim 8 wherein said programmable data cartridge includes title information for each recording and further including a visual display means on which said title information is displayed.

10. The apparatus of claim 7, wherein said musical reproduction unit includes touch sensitive means associated with said array of covers and operatively connected to said control means.

11. The apparatus of claim 10, wherein said touch-sensitive means comprise a plurality of infra-red emitters and detectors arranged along edges of said array, thereby providing a touch-sensitive grid comprising a plurality of intersection points corresponding to respective covers of said array.

12. The apparatus of claim 11, further comprising means for visually indicating to the user regions of said covers corresponding in position to said intersection points.

13. The apparatus of claim 12, wherein each of said photographically reduced covers is positioned within a transparent holder and said transparent holder is releasibly mounted on said musical reproduction unit.

14. The apparatus of claim 12, wherein said apparatus further comprises a transparent cover overlying said photographically reduced covers mounted on said musical reproduction unit and said means for visually indicating comprise marks formed on said transparent cover at predetermined positions, corresponding with said intersection points.

15. The apparatus of claim 7, wherein said musical reproduction unit includes means for illuminating selected ones of said photographically reduced covers responsive to said control means.

16. The musical reproduction unit of claim 6 wherein the digitally encoded records are compact discs.
