Abstract

The invention is an automated storage library including one or more robotic accessors which move upon the surface of a horizontal plane including the openings to storage cells. The accessors are wireless, remotely controlled vehicles. The vehicles employ known tracking mechanism(s) to move between locations within the library. The storage cells are embedded beneath the horizontal surface. The horizontal plane is a floor which is formed by the surface of the storage cells. Openings in the floor are also the access openings to the storage cells. Storage media are raised and lowered into the storage cells by a picker mechanism on the vehicles.

Claims

1. An automated storage library for storing and retrieving a plurality of data storage media therein, the data storage media capable of storing data thereon for use by a computer, the library comprising:

a horizontal floor including uncovered openings therethrough;

a peripheral storage device capable of having one of the data storage media mounted therein for the transmittal of data between the computer and said one of the data storage media;

a plurality of storage cells embedded beneath the floor, each of the storage cells capable of having one of the data storage media stored therein, each one of the data storage media in the storage cells accessible through a different one of the openings in the floor; and

an accessor for transferring, in response to the computer, one of the data storage media between the peripheral storage device and any of the storage cells, the accessor capable of moving over substantially an entire surface of the floor by powered wheel means.

2. The automated storage library of claim 1 wherein the accessor is a wireless, remotely controlled vehicle.

3. The automated storage library of claim 1 wherein the floor includes a printed pattern facilitating positioning of the accessor.

4. The automated storage library of claim 1 wherein the accessor transfers the data storage media between a horizontal position in the peripheral storage device and vertical positions in the storage cells.

5. The automated storage library of claim 1 further comprising a plurality of peripheral storage devices each capable of having one of the data storage media mounted therein, the accessor capable of transferring one of the data storage media between any of the peripheral storage devices and any of the storage cells.

6. An automated storage library for storing and retrieving a plurality of data storage media therein, the data storage media capable of storing data thereon for use by a computer, the library comprising:

a horizontal floor including uncovered openings therethrough;

a peripheral storage device embedded beneath the floor and capable of having one of the data storage media mounted therein for the transmittal of data between the computer and said one of the data storage media;

a plurality of storage cells embedded beneath the floor, each of the storage cells capable of having one of the data storage media stored therein, each of the storage cells accessible through one of the openings in the floor; and

an accessor for transferring, in response to the computer, one of the data storage media between the peripheral storage device and any of the storage cells, the accessor capable of moving over substantially an entire surface of the floor by powered wheel means.

7. The automated storage library of claim 6 wherein the accessor is a wireless, remotely controlled vehicle.

8. The automated storage library of claim 6 wherein the floor includes a printed pattern facilitating positioning of the accessor.

9. The automated storage library of claim 6 further comprising a plurality of peripheral storage devices each embedded beneath the floor and capable of having one of the data storage media mounted therein, the accessor capable of transferring a data storage medium between any of the peripheral storage devices and any of the storage cells.

10. An automated storage library for storing and retrieving a plurality of data storage media therein, the data storage media capable of storing data thereon for use by a computer, the library comprising:

a horizontal floor including openings therethrough and a printed pattern thereon;

a plurality of peripheral storage devices each capable of having one of the data storage media mounted therein for the transmittal of data between the computer and said one of the data storage media, at least one of the peripheral storage devices embedded beneath the floor;

a plurality of storage cells embedded beneath the floor, each of the storage cells capable of having one of the data storage media stored therein, each one of the data storage media in the storage cells accessible through a different one of the openings in the floor; and

a plurality of wireless, remotely controlled vehicles for transferring, in response to the computer, one of the data storage media between any of the peripheral storage devices and any of the storage cells, each vehicle capable of moving over substantially an entire surface of the floor by powered wheel means, the printed pattern on the floor facilitating positioning of each vehicle.

11. The automated storage library of claim 10 wherein the vehicles transfer the data storage media between a horizontal position in at least one of the peripheral storage devices and vertical positions in the storage cells.

12. An automated storage library for storing and retrieving a plurality of data storage media therein, the data storage media capable of storing data thereon for use by a computer, the library comprising:

a horizontal floor including slotted uncovered openings therethrough;

a peripheral storage device capable of having one of the data storage media mounted therein for the transmittal of data between the computer and said one of the data storage media;

a plurality of storage cells embedded beneath the floor, each of the storage cells capable of having one of the data storage media stored vertically therein; and

an accessor for transferring, in response to the computer, one of the data storage media between the peripheral storage device and any of the storage cells, the accessor capable of moving over substantially an entire surface of the floor by powered wheel means and being sized relative to the uncovered openings to pass over the uncovered openings without falling therethrough.

13. The automated storage library of claim 12 wherein the uncovered openings each have a length and a width, the length greater than the width, and the accessor includes wheels for enabling movement upon the floor, the wheels having a width greater than the length of the uncovered openings.

14. An automated storage library for storing and retrieving a plurality of data storage media therein, the data storage media capable of storing data thereon for use by a computer, the library comprising:

a horizontal floor including slotted uncovered openings therethrough and a printed pattern thereon, each of the uncovered openings having a length and a width;

a plurality of peripheral storage devices each capable of having one of the data storage media mounted therein for the transmittal of data between the computer and said one of the data storage media, at least one of the peripheral storage devices embedded beneath the floor;

a plurality of storage cells embedded beneath the floor, each of the storage cells capable of having one of the data storage media stored vertically therein, each one of the data storage media in the storage cells accessible through a different one of the openings in the floor; and

a plurality of wireless, remotely controlled vehicles for transferring, in response to the computer, one of the data storage media between any of the peripheral storage media between any of the peripheral storage devices and any of the storage cells, each vehicle having wheels capable of moving upon the floor, the wheels having a width greater than the length of the uncovered openings, the printed pattern on the floor facilitating positioning of each vehicle.
