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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
73 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 a common divisor 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 address unit.
Claim 2
Dependent Claim
73 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 a common divisor 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 address unit.
Claim 3
Dependent Claim
22 words
A data recording medium according to claim 1, wherein user data of one sector of said first data format is 512 bytes.
Claim 4
Dependent Claim
31 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.
Claim 5
Dependent Claim
105 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 a common divisor 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 address unit.
Claim 6
Dependent Claim
105 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 a common divisor 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 address unit.
Claim 7
Dependent Claim
22 words
A data recording medium according to claim 4, wherein user data of one sector of said first data format is 512 bytes.
Claim 8
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 9
Dependent Claim
117 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, the method comprising the steps of: preliminarily recording an address for each address unit on said recording medium, by selecting a common divisor of said first data amount and said second data amount to be a data amount of an address unit, accessing a sector of said first data format by incrementing said address by a first integer, and accessing a sector of said second data format by incrementing said address by a second integer.
Claim 10
Dependent Claim
117 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, the method comprising the steps of: preliminarily recording an address for each address unit on said recording medium, by selecting a common divisor of said first data amount and said second data amount to be a data amount of an address unit, accessing a sector of said first data format by incrementing said address by a first integer, and accessing a sector of said second data format by incrementing said address by a second integer.
Claim 11
Dependent Claim
121 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, the method comprising the steps of: preliminarily recording an address for each address unit on said recording medium, by selecting a common divisor of said first data amount and said second data amount to be a data amount of an address unit, accessing a sector of said first data format by incrementing said address by a first integer, and accessing a sector of said second data format by incrementing said address by a second integer.
Claim 12
Dependent Claim
121 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, the method comprising the steps of: preliminarily recording an address for each address unit on said recording medium, by selecting a common divisor of said first data amount and said second data amount to be a data amount of an address unit, accessing a sector of said first data format by incrementing said address by a first integer, and accessing a sector of said second data format by incrementing said address by a second integer.
