Abstract: An memory device (HDD) storage system (10) has at least one storing location (16) in which an memory device (18) is received while the memory device is not supplied with an electric power, at least one docking location (22) where the memory device is supplied with the electric power so that data can be stored in the memory device and retrieved from the memory device, and a transport device (30) for transporting the memory device between the shelf (16) and the docking location (22). Alternatively, a switching controller (110) connects a system controller (26) and also a power source (118) to an immovably secured memory device (18).

Abstract: A data storage system or library system 10 has a dust collector 36 in a chamber 24 or interior of the housing 12. The dust collector 36 has a container 48 with first openings 52 and 54 and second openings 68, filters 64 and 66 provided at the first openings 52 and 54, and a fan 70 for forming a stream of air running through the first openings 52 and 54 and the second openings 68. With the system 10, the housing 12 is substantially closed so that substantially no dust enters into the housing 12. Also, dust generated in the housing 12 is effectively collected by the filters 64 and 66.

Abstract: A rotating frame 22 is supported by a stationary frame 21 rotatably by 180 degrees, and in both side plates 22c of the rotating frame 22, there are formed four pairs of guide grooves 25-28 for guiding pallets 9 and slots 32a-32d for moving claw members 30, 31, said slots corresponding to said guide grooves 25-28. On an inner wall of a rear plate 22b of the rotating frame 22, there is provided an up and down movable member 47 which moves downward together with the claw members 30, 31 when the rotating frame 22 is rotated by 180 degrees. Into the first and third guide grooves 25 and 27, there have been previously inserted empty pallets 9 with such a posture that their front surfaces 11 face downward. By moving the claw members 30, 31 along the slots 32b, 32d, the pallets 9 having discs D placed thereon are drawn into the second and fourth guide grooves 26 and 28 such that these pallets 9 are opposed to the upper empty pallets 9.
