Abstract

A collection system using a CD ROM computer system wherein the collection items (or more specifically their unlocking keys) are contained in various floppy disks. With the disks inserted into the computer system, the icons of the collection items on the disks appear on the computer monitor. By (double) clicking on the icon, the unlocking key unlocks the corresponding collection item in the CD ROM program into the hard drive and at the same time the unlocking key is rendered inoperative. A generally reverse process can be used to lock the collection item relative to the hard drive and render the unlocking key operative. The user collects the collection items by unlocking, using a number of floppy disks, the locks in his CD ROM program, which contains the corresponding locks for all of the collection items in the set. When the entire set or a predetermined subset thereof has been collected, the CD ROM program allows the user to play an interactive game related to the collection items. The user can also enjoy a video and/or audio presentation contained in the disk and/or the CD ROM program associated with each of the keys (and thereby the corresponding collection items) by (single) clicking on the appropriate icons. That is, instead of the prior art system of trading paper cards or the like, the user herein trades floppy disks to collect the collection items, and can enjoy audio/visual presentations and interactive computer games also associated with the collected items.

Claims

1. A computer-based collection system, comprising:

a computer system including a disk drive, a hard drive, a user input and a display system;

a program loaded into said computer system, said program including different locked first and second collection items;

a first disk having a first coded key, said first disk after being inserted into said disk drive being capable of unlocking, using said first coded key, said first collection item into said hard drive; and

a second disk having a second coded key, said second disk after being inserted into said disk drive being capable of unlocking, using said second coded key, said second collection item into said hard drive;

wherein said first coded key after unlocking said first collection piece is rendered inoperative and incapable of unlocking a corresponding first collection item in a similar program.

2. The collection system of claim 1 wherein said program is capable, by actuation of said user input, after said first collection item has been unlocked into said hard drive, of relocking said first collection item relative to said hard drive and rendering said first coded key of said first disk operative and capable of again unlocking said first collection item.

3. The collection system of claim 2 wherein said first disk with said first coded key operative allows said first collection item to be fully displayed on said display system and said first disk with said first coded key inoperative is incapable of fully displaying said first collection item on said display system.

4. The collection system of claim 3 wherein said first collection item when prevented from being fully displayed is displayed with visually dimmer display than when fully displayed.

5. The collection system of claim 4 wherein said computer system, said disk drive and said hard drive define, respectively, a first computer system, a first disk drive and a first hard drive;

and further comprising a second computer system including a second disk drive and a second hard drive, a second program similar to said first program and in said second computer system, and wherein said first disk with said first coded key having been rendered operative can be inserted into said second disk drive to unlock using said first coded key a similar first collection item into said second hard drive.

6. The collection system of claim 1 wherein said second coded key after unlocking said second collection piece is rendered inoperative and incapable of unlocking a similar second collection piece in a similar program.

7. The collection system of claim 1 wherein said computer system includes a CD ROM drive operatively connected to said hard drive, and said program is loaded into said computer system by a CD ROM disk into said CD ROM drive.

8. The collection system of claim 7 wherein said first disk includes a first disk program, which includes said first coded key, and which when activated initiates a display, separate from said CD ROM program, on said display system, said display being associated with said first collection item.

9. The collection system of claim 1 wherein said program includes a locked third collection item different from said first and second collection items, and said first disk includes a third coded key adapted to unlock said third collection item into said hard drive.

10. The collection system of claim 1 wherein said first disk includes an identifier on its disk case.

11. The collection system of claim 10 wherein said identifier is a hologram.

12. The collection system of claim 10 wherein said second disk includes a different identifier, different from said identifier of said first disk, on its disk case.

13. The collection system of claim 12 wherein said identifier and said different identifier comprise different serial numbers.

14. The collection system of claim 1 wherein said first and second items form part of a larger set of collection items included in said program.

15. The collection system of claim 1 wherein said user input includes a mouse and a keyboard both operatively connected to said hard drive.

16. The collection system of claim 1 wherein said display system includes a visual display monitor and at least one audio speaker, both operatively connected to said hard drive.

17. The collection system of claim 1 wherein said program includes first and second encryption/decryption algorithms corresponding to said first and second collection items, said first coded key is associated with a complementary first encryption/decryption algorithm complementary to said first encryption/decryption algorithm, and said second coded key is associated with a complementary second encryption/decryption algorithm complementary to said second encryption/decryption algorithm.

18. The collection system of claim 1 wherein said program includes an interactive computer game which a user can play using said user input only after said first and second collection items have been unlocked into said hard drive.

19. The collection system of claim 1 wherein said first disk includes a third coded key, and further comprising a third disk containing said third coded key but not said first and second coded keys.

20. A computer-based collection method, comprising the steps of:

providing a computer system including a disk drive, a hard drive, a CD ROM drive, a user input and a display system;

providing a CD ROM program loaded into said CD ROM drive, the program including different locked first and second collection items;

providing first and second disks having respective first and second coded keys;

inserting the first disk into the disk drive;

instructing the computer system via the user input to unlock the first collection item onto the hard drive using the first coded key of the inserted first disk;

inserting the second disk into the disk drive; and

instructing the computer system via the user input to unlock the second collection item, into the hard drive using the second coded key of the inserted second disk.

21. The collection method of claim 20 wherein the program includes an interactive computer game, and further comprising after said second instructing step and only after a specified series of collection items, including at least the first and second collection items, have been unlocked into the hard drive using respective coded keys contained on disks, playing the computer game using the user input.

22. The collection method of claim 21 wherein said playing includes playing the computer game on-line with another player.

23. The collection method of claim 20 further comprising inserting a third disk having therein a coded key into the disk drive;

viewing on the display system a collection item associated with the coded key of the third disk; and

without rendering the coded key inoperative, removing the third disk from the disk drive and trading it with another person for at least a fourth disk having a coded key therein.

24. The collection method of claim 20 wherein said first-mentioned instructing step renders the first coded key inoperative and incapable of unlocking a similar first collection piece in a similar program.

25. The collection method of claim 24 further comprising after said firstmentioned instructing step, removing the first disk from the disk drive, and thereafter inserting a disk having an inoperative first coded key into the disk drive, and instructing the computer system to relock the first collection item and render the inoperative first coded key operative and capable of subsequently unlocking the first collection item.

26. The collection method of claim 25 further comprising after said rendering the first coded key operative, inserting the disk into a different computer system and unlocking a corresponding first collection item therein.
