Claims
- 1. A method of operating a media library wherein the media library has a linear array of receptacles, each of the receptacles having an outer opening for enabling manual access for inserting and removing a media cartridge into and from said each receptacle, each said receptacle having an inner opening for enabling automatic access for inserting and removing a media cartridge into and from said each receptacle; a media cartridge device disposed adjacent one end of said columnar array, said media cartridge device having a spindle for rotatable supporting a media medium in each of said media cartridges and a transducer means for being in a transducing relationship with a media medium supported on said spindle; accessing means extending co-extensively with said columnar array and having a media cartridge holder movably disposed with respect to said columnar array and said media cartridge device, said holder removing and inserting one of said media cartridges at a time from and to said receptacles and for carrying a removed one of said media cartridges to said media cartridge device for placing one of said media on said spindle for rotation therewith in a play position on said media cartridge device, said holder while mounting said removed one of said media cartridges being disposed in said media cartridge device that is remote from all of said receptacles; manual control means having an input-output (IO) switch and a display; automatic control means connected to said media cartridge device, to said accessing means and to said manual control means, including steps of:
- while said holder is disposed along said array and being remote from said media cartridge device, locking said cartridges against manual removal through said outer openings, respectively;
- while said holder is disposed adjacent to said media cartridge device, in said media library, automatically unlocking all of said cartridges for enabling manual removal and insertion from and into said receptacles through said outer openings, respectively;
- first manually, by an operator, actuating said IO switch for signaling that manually inserting and removing predetermined ones of said cartridges into and from said receptacles, respectively, through said outer openings is to occur;
- in said automatic control means:
- first sensing that said IO switch was actuated;
- sensing whether or not said holder is disposed adjacent to said media cartridge device;
- responding to said sensing indicating that said holder is not disposed adjacent to said media cartridge device to actuate said accessing means to move said holder into said media cartridge device;
- then, signaling said display to indicate that cartridges may be manually removed and inserted into said array;
- keeping said holder disposed at said media cartridge device;
- manually, by an operator, removing and inserting predetermined ones of said media cartridges in predetermined ones of said receptacles;
- in said array, sensing and indicating a first one of said cartridge removals or insertions from or into any one of said receptacles;
- second, after said removing and inserting predetermined ones of said media cartridges, manually, by an operator, actuating said IO switch for indicating that said holder may be moved away from said media cartridge device:
- then, in said automatic control means responding to said second manually actuating said IO switch;:
- second sensing and indicating that said IO switch was actuated after said first sensing step;
- reading said indications of said first one of said cartridge removals and insertions;
- as an inventory updating step, actuating said accessing means to sequentially move said cartridge holder to each of said predetermined ones of said receptacles to fetch a respective one of said media cartridges, as fetched media cartridge, stored in respective ones of said predetermined ones of said receptacles for transporting each said fetched media cartridge to said media cartridge device for reading an identification in said fetched media cartridges, respectively and then returning said fetched media cartridges to respective ones of said predetermined ones of said receptacles.
- 2. The method set forth in claim 1, further including steps of:
- in said array, before performing said inventory updating step, locking said receptacles to prevent manually moving or receiving any of said media cartridges out of or into any of said receptacles through said outer opening;
- in said automatic control means, actuating said cartridge holder to move to be adjacent said media cartridge device;
- in said array; when said cartridge holder arrives at said media cartridge device, unlocking said receptacles to enable said moving or receiving any of said media cartridges out of or into any of said receptacles through said outer opening;
- after said cartridge holder arrives at said media cartridge device, turning off power to said accessing means;
- after said power to accessing means is turned off, manually, by an operator, inserting and/or removing predetermined ones of said cartridges from or to second predetermined ones of said receptacles;
- in said array, mechanically sensing and latching a mechanical indication of a first one of said manually inserted or removed certain ones of said cartridges to or from said second predetermined ones of said receptacles;
- responding to said indicating that said holder may be moved from said media cartridge device to turn on power to said accessing means;
- in said array, sensing said mechanically latched mechanical indications; and
- in said automatic control means responding to said sensed mechanical indications to perform said updating inventory step.
