ABSTRACT:
An apparatus for reproducing a multi-layer disc which has a first layer containing a recorded multi-bit digital signal quantized at a first sampling frequency and a second, layer containing a recorded 1-bit digital signal quantized at a second, higher sampling frequency. The apparatus includes a layer switching device capable of executing an instruction to selectively switch the signal reproduction of the first layer and that of the second layer; and a reproduction controller for preferentially setting the signal reproduction from either the first or second layer when the multi-layer disc is loaded in the apparatus, and in response to a manipulation of the layer switching device, selectively switching the setting of the signal reproduction relative to the first and second layers. A display is also incorporated to discriminably indicate thereon the layer selected by a manipulation of the layer switching device, hence enabling the user to recognize the layer being currently reproduced.
