Abstract
Abstract An address unit is provided so that integer multiples of the address unit correspond to respective sector capacities of plural kinds of formats (such as the ISO format and the CD format) which are different in sector size. In this fashion, by multiplying the address unit by an integer, a sector of a respective one of plural kinds of formats can readily be accessed to.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
75 words
A data recording medium capable of recording data of a first data format in which one sector comprises a first data amount and data of a second data format in which one sector comprises a second data amount, wherein one of common divisors of said first data amount and said second data amount is selected to be a data amount of an address unit and an address is preliminarily recorded for each the address unit.
Claim 2
Dependent Claim
25 words
A data recording medium according to claim 1, wherein user data of one sector of said first data format is of units of 512 bytes.
Claim 3
Dependent Claim
32 words
A data recording medium according to claim 1, or 2, wherein user data of one sector of said second data format corresponds to data of 98 frames of a compact disc (1,2,3).
Claim 4
Dependent Claim
107 words
A data recording medium capable of recording data of a first data format in which one sector comprises a first data amount and data of a second data format in which one sector comprises second data amount, wherein servo information is preliminarily recorded for each segment which is obtained by dividing data of one sector in data format, and wherein one of common divisors of said first data amount and said second data amount which is an integer multiple of data amount in said segment is selected to be a data amount of an address unit and an address is preliminarily recorded for each the address unit.
Claim 5
Dependent Claim
25 words
A data recording medium according to claim 4, wherein user data of one sector of said first data format is of units of 512 bytes.
Claim 6
Dependent Claim
21 words
A data recording medium according to claim 5, wherein data in one segment of said first data format is 16 bytes.
Claim 7
Dependent Claim
119 words
A data recording method for recording data of a first data format in which one sector comprises a first data amount and data of a second data format in which one sector comprises a second data amount onto the same recording medium, wherein on said recording medium, by selecting one of common divisors of said first data amount and said second data amount to be a data amount of an address unit, an address is preliminarily recorded for each the address unit, a sector of said first data format is accessed to by incrementing said address by a first integer, and a sector of said second data format is accessed to by incrementing said address by a second integer.
Claim 8
Dependent Claim
123 words
A data reproducing method for reproducing data from a recording medium on which data of a first data format in which one sector comprises a first data amount and data of a second data format in which one sector comprises a second data amount are recorded, wherein on said recording medium, by selecting one of common divisors of said first data amount and said second data amount to be a data amount of an address unit, an address is preliminarily recorded for each the address unit, a sector of said first data format is accessed to by incrementing said address by a first integer, and a sector of said second data format is accessed to by incrementing said address by a second integer.
