A removable mechanism for a hard drive is revealed. The removable mechanism includes an upper substrate and a base plate hanged and sliding below the upper substrate, and a control handle and a sliding board are set between the upper substrate and the base plate to carry each other. The control handle controls a pivot element sliding on an opening of the base plate. By carrying each other to carry a stop element of the base plate, the stop element slides on a concave opening for dismounting a storage device inserted to the removable drawing mechanism. Thereby, the present application is convenient for dismounting the storage device.

Provided is a disc storage apparatus that includes a case including an opening on an upper surface of the case and capable of storing N rows of stacked M disc-shaped recording media (N and M each indicate a positive integer of two or greater), a tray cover that slides from a rear end of the case and cover the opening, and a locking mechanism that locks a state of the opening being covered.

An optical disc drive (ODD) including a housing, a tray, a panel, a first linkage, and a second linkage is provided. The tray is movably disposed at the housing to move into or move out of the housing. The panel is connected to the tray and located at a side of the housing. The first linkage is rotatably disposed on the panel and located between the housing and the panel. The second linkage is rotatably disposed on the panel and located between the first linkage and the panel. By rotating the first linkage with respect to the panel in a first rotating direction, the second linkage is pushed by the first linkage and rotates with respect to the panel in a second rotating direction opposite to the first rotating direction so as to actuate the tray to move out of the housing.
