Abstract
Abstract A reproducing apparatus for a disc in which data recorded on an optical disc (1) are read out by an optical pickup (7) and reproduced is disclosed. Before start of reproduction, it is determined if the disc (1) loaded into the apparatus is a data disc on which information data such as letter or character data or picture data are recorded, or an audio disc on which audio signals are recorded, and the playback mode is automatically selected as a function of the type of the optical disc (1) loaded into the apparatus. At the start time of the reproducing operation from the disc (1), the type discriminating data recorded on the disc (1) are read out and, as a function of the contents of the type discriminating data, switching is made automatically between the data reproducing operation and the audio signal reproducing operation, while the type of the optical disc (1) is displayed (27) on the display section (51, 54) on the basis of the type discriminating data.

Dependent Claim
107 words
The reproducing apparatus according to claim 1, wherein said control means comprises discriminating means (8, 11, 12) for shifting said optical pickup (7) towards the innermost periphery of the disc (1) at the time of starting the reproducing operation to read out the type discrimination data recorded towards the innermost periphery of the disc (1) by said optical pickup (7) to discriminate the type of the optical disc (1) on the basis of said type discrimination data, and switching means (5, 15) for automatically switching between the data reproducing operation and the audio signal reproducing operation on the basis of the detection output from said discriminating means.
Claim 3
Dependent Claim
36 words
The reproducing apparatus according to claim 1 or 2, wherein said control means (3, 4) generates display (27) control signals indicating the type of the optical disc (1) on the basis of said type discrimination data.
Claim 4
Dependent Claim
46 words
The reproducing apparatus according to claim 3, wherein, when the type discrimination data indicate that the disc (1) is the optical data disc, said control means transmit said display control signal before moving said optical pickup (7) to a record start portion of the disc (1).
Claim 5
Dependent Claim
49 words
The reproducing apparatus according to claim 3, wherein, when said type discriminating data indicate that the disc (1) is an optical disc on which audio signals are recorded, said control means transmit signal indicating the total record time and number of airs in addition to said display control signal.
Claim 6
Dependent Claim
93 words
A reproducing apparatus for a disc in which data recorded on an optical disc (1) are read out by an optical pickup (7) for reproduction, comprising a main body (44) of the apparatus including control means (3, 4) for reading out type discriminating data on the disc (1) at the time of starting disc data reproduction for automatically switching between a data reproducing operation and an audio signal reproducing operation on the basis of said type discrimination data, and a display section (51, 54) having its display contents switched by said control means.
Claim 7
Dependent Claim
34 words
The reproducing apparatus according to claim 6, wherein said control means display (27) the type of the optical disc (1) on said display section (51, 54) on the basis of said type discrimination data.
Claim 8
Dependent Claim
54 words
The reproducing apparatus according to claim 6 or 7, wherein, when the type discriminating data indicates that the disc (1) is an optical data disc, said control means (3, 4) displays that effect on said display section (50, 54) before moving said optical pickup (7) to a record start portion of the disc (1).
Claim 9
Dependent Claim
58 words
The reproducing apparatus according anyone of claims 6 to 8, wherein, when said type discriminating data indicate that the disc (1) is an optical disc on which audio signals are recorded, said control means (3, 4) cause that effect, the total record time and the number of airs to be displayed (27) on said display section (51, 54).
