Abstract
Abstract The present invention relates to a recording method and a recording apparatus for use with a disc having a data area in which data has been recorded and an area for recording control information (i.e., Table of Contents information) for accessing a head to the data area. The recording apparatus comprises means for inhibiting the fetching of a disc if the control information has not been recorded in a predetermined area of the disc. Further, by providing a memory for storing the control information, the invention permits the accessing of a head to the data area in accordance with the content of the memory. Thus, information recorded on the disc before the control information is recorded onto a predetermined area on the disc can be reproduced.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
120 words
A disc recording apparatus for recording information onto a disc, wherein the disc has a data area for recording data in a predetermined position, and a control information area for recording control information for use in accessing a head to the predetermined position, comprising: state conversion means for converting the disc recording apparatus from a first state in which recording is executed, into a second state in which loading of the disc from the disc recording apparatus is executed; and control means connected to the state conversion means for inhibiting the state conversion means from converting the disc recording apparatus into the second state if the control information is not recorded in the control information area during the first state.
Claim 2
Dependent Claim
120 words
A disc recording apparatus for recording information onto a disc, wherein the disc has a data area for recording data in a predetermined position, and a control information area for recording control information for use in accessing a head to the predetermined position, comprising: state conversion means for converting the disc recording apparatus from a first state in which recording is executed, into a second state in which loading of the disc from the disc recording apparatus is executed; and control means connected to the state conversion means for inhibiting the state conversion means from converting the disc recording apparatus into the second state if the control information is not recorded in the control information area during the first state.
Claim 3
Dependent Claim
17 words
A disc recording apparatus according to claim 1, wherein the control information is a table of contents.
Claim 4
Dependent Claim
60 words
A disc recording apparatus according to claim 1, wherein the state conversion means includes a disc loading and unloading tray mechanism, wherein the control means comprises a command means for commanding the tray mechanism to unload the disc, and wherein the control means executes recording of the control information in response to such an unload command from the command means.
Claim 5
Dependent Claim
58 words
A disc recording apparatus according to claim 1, wherein the control means comprises detecting means for detecting that no control information has been recorded in the control information area, and wherein the control means inhibits the state conversion means from converting the disc recording apparatus into the second state in response to an output of the detecting means.
Claim 6
Dependent Claim
30 words
A disc recording apparatus according to claim 1, wherein the disc recording apparatus comprises a command means for commanding the end of the recording of information into the data area.

Claim 9
Independent Claim
74 words
A method for controlling loading of a disc on which information has been recorded in a predetermined position, wherein the disc has a control information area for recording control information for use in accessing a head to the predetermined position, including the step of: blocking loading of the disc, after information has been recorded into the data area, if control information corresponding to the information is not first recorded into the control information area.
Claim 10
Independent Claim
74 words
A method for controlling loading of a disc on which information has been recorded in a predetermined position, wherein the disc has a control information area for recording control information for use in accessing a head to the predetermined position, including the step of: blocking loading of the disc, after information has been recorded into the data area, if control information corresponding to the information is not first recorded into the control information area.
Claim 11
Dependent Claim
54 words
A method according to claim 8, wherein the control information is stored in a memory, and including the step of: reproducing, prior to the recording of the control information into the control information area on the disc, the information recorded in the data area in response to the control information stored in the memory.
Claim 12
Dependent Claim
40 words
