Description
Technical Field
The present invention relates to the field of optical disc library technology, and in particular, to an optical disc library and a method for carrying optical discs.
Background
The optical disk library is an information storage device which takes a large-capacity optical disk as a storage medium, and is suitable for long-term storage of mass data. A typical optical disc library consists of a media capacity unit, an optical drive group unit and a media carrying unit.
In modern information storage facilities, it is very popular to deploy an environment with 19-inch cabinets, where various devices are mounted on racks in the cabinets of standard size, so that the entire equipment environment is very clean and the wiring and expansion of the devices are very convenient. It is very difficult for the optical disc library to be made into a product form which can be fixed on a rack of a 19-inch standard cabinet. The main reason is the limitation of the volume of standard half-high drives. When the arrangement of the optical drive in the 19-inch standard rack equipment is considered, two adverse factors are involved, namely, the length of the standard optical drive is considered, and the occupied space when the optical drive tray is opened is also considered; secondly, in order to improve the read-write speed of the device, a large number of optical drives need to be configured and can work in parallel. These two factors make the placement of the optical disc drive units in the rack-type optical disc library difficult to be implemented effectively.
Some products achieve this by reducing the size of the optical drive in order to achieve a more compact arrangement, but the disadvantages of this approach are obvious, since the versatility of the optical drive is sacrificed.

The set of optical drives 20 includes a plurality of optical drives 20 aligned in the height direction of the optical disc library, and each optical drive 20 is provided with an optical drive tray 21 capable of being ejected in the depth direction of the optical disc library. The dragging device 30 is used for dragging the designated optical disc drive 20 along the width direction of the optical disc library to a first preset position (see the position of the dashed line box in fig. 1) under control. The robot 40 is used to complete the carrying of the optical disc between the disc cartridge 11 and the optical drive tray 21 ejected from the optical drive 20 located at the first predetermined position.
In this embodiment, the optical disc drive 20 is disposed at a position aligned with the optical disc cartridge 10 in the height direction or the depth direction of the optical disc cartridge, and the optical disc drive 20 is set to eject the optical disc drive tray 21 along the depth direction of the optical disc cartridge, so that the optical disc drive 20 does not occupy the width direction of the optical disc cartridge and shares the optical disc drive tray 21 of the optical disc drive 20 with the occupied space of the original manipulator 40, the overall structure is compact in arrangement, and further the space is saved, which is beneficial for the optical disc cartridge to be disposed in a 19-inch chassis. And the position and the direction of the optical drive 20 are skillfully arranged without modifying the optical drive 20, and the common optical drive 20 can still be used, so that the universality of the optical drive 20 is kept, the application range is wide, and the manufacturing cost is low.

A supporting plate 51 may be disposed between the two sets of optical drives 20 for supporting the optical drives 20 dragged out to the first predetermined position.
Fig. 6 is a flowchart of a method for carrying an optical disc according to an embodiment of the present invention. As shown in fig. 6, the present invention further provides a method for carrying an optical disc, which is used in any optical disc library, and the method comprises:
step S10: the control manipulator 40 moves to the designated disc box 11, extracts the disc box tray 101 of the designated disc box 11, grabs a plurality of optical discs aligned to the same vertical line in the disc box tray 101 of the designated disc box 11, and finally pushes the disc box tray 101 of the designated disc box 11, so that the target optical disc to be read and written is positioned at the lowest part of the plurality of optical discs;
step S20: controlling the manipulator 40 to move to a third preset position (see the position of the manipulator 40 in fig. 3) so that the centers of all the optical discs grabbed by the manipulator 40 and the optical disc drive tray 21 ejected by the specified optical disc drive 20 located at the first preset position are located on the same vertical line;
step S30: controlling the dragging device 30 to drag the designated optical disc drive 20 to a first preset position;
step S40: controlling a designated optical drive 20 located at a first preset position to eject an optical drive tray 21;
step S50: controlling the manipulator 40 to release the target optical disc into the optical disc drive tray 21 ejected by the designated optical disc drive 20;
step S60: controlling the designated optical drive 20 to close the optical drive tray 21;
step S70: controlling the dragging device 30 to drag the designated optical drive 20 to the original position so as to perform a read-write operation on the optical disc placed in the designated optical drive 20 at the original position;
step S80: the control robot 40 replaces the remaining optical disk in the disk cartridge tray 101 of the designated disk cartridge 11. The specific operation process of step S80 is the reverse of step S10, and is not described herein again.
It should be noted that, since a column of optical discs aligned along the Z direction is usually disposed in one disc cartridge tray 101, when a specific optical disc (i.e. a target optical disc) is grasped, all optical discs above the target optical disc need to be taken out together, and then the bottommost target optical disc needs to be released into the optical drive 20. Since the reading and writing operations of the optical discs may be continuous, for example, data on each optical disc at different positions in different disc cartridges 11 needs to be read sequentially, at this time, the manipulator 40 needs to be controlled to put other optical discs that have released the target optical disc back to the original position first, and then sequentially grab the other optical discs according to the command.
Fig. 7 is a flowchart of a method for carrying an optical disc according to another embodiment of the present invention. As shown in fig. 7, in a further embodiment, the method for carrying an optical disc further includes:
step S90: after the designated optical drive 20 finishes the read-write operation, controlling the manipulator 40 to grab a plurality of optical disks positioned above the target optical disk and move to a third preset position;
step S100: controlling the dragging device 30 to drag the designated optical disc drive 20 to a first preset position;
step S110: controlling the appointed optical drive 20 to eject an optical drive tray 21;
step S120: the manipulator 40 is controlled to grasp the target optical disk and replace all the grasped optical disks in the disk cartridge tray 101 of the designated disk cartridge 11. The specific operation process of the step S120 of retrieving the optical disc is the reverse of the step S10, and is not described herein again.
Similarly, when retrieving the target optical disc, the target optical disc needs to be replaced, and therefore all optical discs located above the target optical disc in the designated disc cartridge 11 need to be grabbed first, and then the target optical disc needs to be grabbed, so that the optical discs are still placed in the same order as before.
The optical disc library is arranged in the manner of the previous arrangement, so that the carrying method of the optical disc of the embodiment is efficient and simple.
Thus, it should be appreciated by those skilled in the art that while a number of exemplary embodiments of the invention have been illustrated and described in detail herein, many other variations or modifications consistent with the principles of the invention may be directly determined or derived from the disclosure of the present invention without departing from the spirit and scope of the invention. Accordingly, the scope of the invention should be understood and interpreted to cover all such other variations or modifications.
