A disc driving apparatus has two bases. Both bases swing about their parallel shafts provided at the same side of the bases between positions where the bases chuck a disc-shaped recording medium and positions where they release the medium. A member for rotating the medium is provided for one of the bases, and another member for connecting the medium and the member in order to rotate them together is provided for the other of the bases. The disc driving apparatus also has a pickup for accessing the medium, a chucking mechanism for chucking the medium, a pickup moving mechanism, and a locking mechanism. The pickup can be moved in the radial direction of the medium. The pickup moving mechanism moves the pickup in the radial direction of the medium when the chucking mechanism releases the medium. The locking mechanism locks the movement of the pickup after it is moved to a specified position by the pickup moving mechanism.

In a video cassette auto-changer which includes a plurality of reproducing and/or recording devices or VTRs, and a plurality of cassette storage bins arrayed in horizontal and vertical directions and each adapted to store a cassette therein; a cassette transporting apparatus for selectively transporting cassettes between the storage bins and the VTRs comprises fixed horizontal upper and lower guide rails along which upper and lower sliders are movable, a movable guide rail extending vertically between the sliders and pivotally connected to the latter at ends of the movable guide rail, a carriage movable vertically along the movable guide rail, a horizontal drive connected with the sliders for moving the carriage in the direction along the fixed guide rails and a vertical drive for moving the carriage along the movable guide rail. Elongated, flexible electrical connecting members or harnesses are provided for applying electrical control signals to horizontally and vertically movable components of the cassette transporting apparatus and are associated with slack take-up devices so that such electrical connecting members can accommodate and will not interfere with substantially vertical and horizontal movements of the carriage.
