Abstract
Abstract In constructing a list of recorded data recorded onto a disk (4), a point of starting the recording of finally recorded data is found from time record data of the final record, and the preceding data area is sought to find a point of starting the recording of the data. The seeking operation is repeated to construct the list within short periods of time on a time table under a system controller (1). The list thus prepared is then recorded onto a list-recording area of the disk (4). AO - Start A1 - Is there a disk? A2 - La there a list? A3 - Are there recorded data? A4 - Detect a point of final record. A5 - Sead flast, Mnlast, IMnlast. A13 - Seek T3. A16 - sead the list. 120 - and

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
98 words
A method of constructing a list of recorded data in a postscript type optical disk comprising the steps of: detecting a point of ending the recording of recorded data recorded onto a disk; reading time code data at said point by ending the recording; obtaining a point of starting the recording through subtraction of the recording time of the last recorded data from the overall recording time according to said time code data; and storing the obtained point of starting the recording in a time table of the pertinent data number, thereby constructing a list of recorded data.
Claim 2
Independent Claim
98 words
A method of constructing a list of recorded data in a postscript type optical disk comprising the steps of: detecting a point of ending the recording of recorded data recorded onto a disk; reading time code data at said point by ending the recording; obtaining a point of starting the recording through subtraction of the recording time of the last recorded data from the overall recording time according to said time code data; and storing the obtained point of starting the recording in a time table of the pertinent data number, thereby constructing a list of recorded data.
Claim 3
Dependent Claim
103 words
A method of constructing a list of recorded data in a postscript type optical disk according to claim 1, wherein a pointer showing a data number to be searched next is initialized with the data number of said last recorded data, a point of starting the recording of recorded data of the data number shown by said pointer is read out from said time table and stored in a register for seeking a value with a predetermined off-set from the read-out point of starting the recording, and the point shown by the value of the register contents is sought by advancing said pointer.
Claim 4
Dependent Claim
67 words
A method of constructing a list of recorded data in a postscript type optical disk according to claim 2, wherein the seek point is compensated for the case when the data number after the seeking fails to coincide with the pointer, while when said data number coincides with said pointer, a point of starting the recording of said data is obtained and stored in said time table.
Claim 5
Dependent Claim
36 words
A method of constructing a list of recorded data in a postscript type optical disk according to claim 2, wherein the point of starting the recording of each data is obtained by repeating the seeking operation.
Claim 6
Independent Claim
250 words
A method of recording a list of recorded data in a postscript type optical disk comprising the steps of: detecting a point of ending the recording of recorded data recorded onto a disk; reading time code data at said point of ending the recording; obtaining a point of starting the recording through subtraction of the recording time of the last recorded data from the overall recording time according to said time code data; storing the obtained point of starting the recording in a time table of the pertinent data number; initializing a pointer representing a data number to be searched next with the data number of said last recorded data; reading out the point of starting the recording of recorded data of the data number represented by the pointer from said time table; storing a point for seeking a value with a predetermined off-set from the read-out point of starting the recording in a register; seeking the point of the value in said register by advancing said pointer; effecting compensation for the seek point when the data number after the seeking fails to coincide with the pointer while obtaining the point of starting the recording of the pertinent data; and storing it in said time table when the data number coincides with the pointer; and repeating the seeking operation to obtain the point of starting the recording of each data, thereby constructing a list of recorded data and recording it in a list area of the postscript type optical disk.
Claim 7
Independent Claim
250 words
A method of recording a list of recorded data in a postscript type optical disk comprising the steps of: detecting a point of ending the recording of recorded data recorded onto a disk; reading time code data at said point of ending the recording; obtaining a point of starting the recording through subtraction of the recording time of the last recorded data from the overall recording time according to said time code data; storing the obtained point of starting the recording in a time table of the pertinent data number; initializing a pointer representing a data number to be searched next with the data number of said last recorded data; reading out the point of starting the recording of recorded data of the data number represented by the pointer from said time table; storing a point for seeking a value with a predetermined off-set from the read-out point of starting the recording in a register; seeking the point of the value in said register by advancing said pointer; effecting compensation for the seek point when the data number after the seeking fails to coincide with the pointer while obtaining the point of starting the recording of the pertinent data; and storing it in said time table when the data number coincides with the pointer; and repeating the seeking operation to obtain the point of starting the recording of each data, thereby constructing a list of recorded data and recording it in a list area of the postscript type optical disk.
