Abstract
Abstract Recordable areas are recorded such that, if a recordable area exists on the outermost position of the disc, it is made into the head recordable area. The other recordable areas are linked from the inner peripheral side toward the outer peripheral side in order of address. With this method, the audio-recording is executed such that the segment division is minimized and the distance between segments is minimized. This makes it possible to shorten the segment access time and minimize the number of accessing operations required. In this way, sound-interruption and the deterioration of the shock-proof function in reproducing action can be prevented.

Claims Analysis
Total Claims: 17
Claim 1
Independent Claim
116 words
A recording/reproducing apparatus for recording information on a recordable disc medium having an inner periphery, an outer periphery, and at least one recordable area, the apparatus comprising: storing means for storing addresses of recordable areas and sequential link information which provides an order for the recordable areas starting from a first recordable area; determining means for determining whether an area at the outer periphery of the disc medium is a recordable area; and control means for changing the sequential link information in the storing means so that when the determining means determines that the area at the outer periphery is a recordable area, then the recordable area at the outer periphery is the first recordable area.
Claim 2
Dependent Claim
116 words
A recording/reproducing apparatus for recording information on a recordable disc medium having an inner periphery, an outer periphery, and at least one recordable area, the apparatus comprising: storing means for storing addresses of recordable areas and sequential link information which provides an order for the recordable areas starting from a first recordable area; determining means for determining whether an area at the outer periphery of the disc medium is a recordable area; and control means for changing the sequential link information in the storing means so that when the determining means determines that the area at the outer periphery is a recordable area, then the recordable area at the outer periphery is the first recordable area.
Claim 3
Dependent Claim
15 words
The apparatus according to claim 1, wherein the storing means is a random access memory.
Claim 4
Dependent Claim
82 words
The apparatus according to claim 1, wherein when the determining means determines that the area at the outer periphery is a recordable area and the recordable area at the outer periphery is made the first recordable area by the control means, then the control means further changes the sequential link information so that the recordable areas after the first recordable area are ordered starting from a recordable area nearest the inner periphery and proceeding toward the outer periphery of the disc medium.
Claim 5
Dependent Claim
66 words
The apparatus according to claim 1, wherein, when the determining means determines that the area at the outermost periphery of the disc medium is not a recordable area, then the control means changes the sequential link information so that the recordable area nearest the inner periphery is the first recordable area and the order of recordable areas proceeds toward the outer periphery of the disc medium.
Claim 6
Dependent Claim
35 words
The apparatus according to claim 1, wherein the determining means for determining whether an area at the outer periphery of the disc medium is a recordable area whenever an erasing or overwrite operation is performed.
Claim 7
Dependent Claim
33 words
The apparatus according to claim 1, further comprising: recording means for recording data on the disc medium starting from the first recordable area, and proceeding in the order of the sequential link information.
Claim 8
Dependent Claim
146 words
In combination, a recordable disc medium and a recording/reproducing apparatus for recording information on the recordable disc medium having an inner periphery, an outer periphery, and at least one recordable area, the apparatus comprising: storing means for storing addresses of recordable areas and sequential link information which provides an order for the recordable areas starting from a first recordable area; determining means for determining whether an area at the outer periphery of the disc medium is a recordable area; and control means for changing the sequential link information in the storing means so that when the determining means determines that the area at the outer periphery is a recordable area, then the recordable area at the outer periphery is the first recordable area; and the recordable disc medium further comprises: a table of contents for storing the addresses of recordable areas and the sequential link information.
Claim 9
Dependent Claim
146 words
In combination, a recordable disc medium and a recording/reproducing apparatus for recording information on the recordable disc medium having an inner periphery, an outer periphery, and at least one recordable area, the apparatus comprising: storing means for storing addresses of recordable areas and sequential link information which provides an order for the recordable areas starting from a first recordable area; determining means for determining whether an area at the outer periphery of the disc medium is a recordable area; and control means for changing the sequential link information in the storing means so that when the determining means determines that the area at the outer periphery is a recordable area, then the recordable area at the outer periphery is the first recordable area; and the recordable disc medium further comprises: a table of contents for storing the addresses of recordable areas and the sequential link information.
Claim 10
Dependent Claim
