A disc grabbing device adapted to a disc archive system for grabbing at least one disc is provided. The disc grabbing device includes a center cylinder, a drive controller and a detection device. When the disc is grabbed by the disc grabbing device, the center cylinder passes through the center hole of the disc. The drive controller is configured to control the disc grabbing device to grab the disc. The detection device is electrically connected to the drive controller to detect a surface of a disc placed on a disc tray to be grabbed, and to correspondingly transmit a drive stop signal to the drive controller to stop the operation of the disc grabbing device.

A disc grabbing device including a support body, a drive shaft, multiple first planetary gears, a center gear, multiple second planetary gears and a driver is provided. The support body includes a plate and a center column. When the disc grabbing device grabs the discs, the center column is located in the center holes of the discs. The drive shaft is rotatably disposed on the plate. The first planetary gears are respectively engaged with the drive shaft and connected to multiple first levers for driving the first levers to rotate. The second planetary gears are respectively engaged with the center gear and connected to multiple second levers for driving the second levers to rotate. The driver concurrently drives the drive shaft and the center gear to rotate the first planetary gears and the second planetary gears synchronically and make the first levers and the second levers rotate synchronically.
