Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
132 words
A data recording method for recording. onto a record medium specified for recording data of a sector size A thereon. data of a different sector size B, comprising the steps of: adding, in order to record mB data into a record unit area of the record medium consisting of n sectors, n being an integral number equal to or greater than 1, m being an integral number which is equal to or greater than 1 and satisfies the relationship of nA > mB, at least an error correction code or an error detection code to the mB data using the region of nA - mB of the record unit area of the record medium; and recording the resultant data into the record unit area of the n sectors of the record medium.
Claim 2
Dependent Claim
23 words
A data recording method according to claim 1, wherein data of the sector size A are user data of units of 512 bytes.
Claim 3
Dependent Claim
25 words
A data recording method according to claim 2, wherein the data of the sector size B are data for 98 frames of a compact disk.
Claim 4
Dependent Claim
46 words
A data recording method according to claim 3, wherein user data in the data for 98 frames of the compact disk are divided into a plurality of data groups, and an error detection code or codes are added to data of each of the data groups.
Claim 5
Dependent Claim
42 words
A data recording method according to claim 4. wherein the data of the plurality of data groups are divided depending upon whether the data belong to an odd-numbered channel or an even-numbered channel and/or the data are odd-numbered data or even-numbered data.
Claim 6
Dependent Claim
52 words
A data recording method according to claim 5, wherein the plurality of data groups are divided into an odd-numbered data group or groups and an even-numbered data group or groups. and a parity or parities for error correction are added between the odd-numbered group or groups and the even-numbered group or groups.
Claim 7
Dependent Claim
139 words
A data recording method for recording, onto a record medium specified for recording data of a sector size A thereon, data of a different sector size B, comprising the steps of: dividing, in order to record mB data into a record unit area of the record medium consisting of n sectors, n being an integral number equal to or greater than 1, m being an integral number which is equal to or greater than 1 and satisfies the relationship of nA > mB, the mB data into a plurality of data groups: adding at least an error detection code to each of the data group using the region of nA - mB of the record unit area of the record medium; and recording the resultant data into the record unit area of the n sectors of the record medium.
Claim 8
Dependent Claim
42 words
A data recording method according to claim 7, wherein the data of the plurality of data groups are divided depending upon whether. the data belong to an odd-numbered channel or an even-numbered channel and/or the data are odd-numbered data or even-numbered data.
Claim 9
Dependent Claim
52 words
A data recording method according to claim 8, wherein the plurality of data groups are divided into an odd-numbered data group or groups and an even-numbered data group or groups. and a parity or parities for error correction are added between the odd-numbered group or groups and the even-numbered group or groups.
