Abstract
Abstract A method of performing data compression of audio data and sequentially recording the data on a disk in units of the data, each unit being formed of a predetermined amount of the data. In the method, there is provided a means for detecting a breakpoint of the audio data. The audio data is continuously recorded by joining, even at the breakpoint, the data preceding and subsequent to the breakpoint, thereby forming the unit data. A piece of information indicating the position of the breakpoint is recorded on the disk. When an operation to suspend or stop the recording operation has been made, the last data immediately before the suspended or stopped point is included in the unit data and recorded as a portion of the unit data. The following data is recorded started from new unit data. When the last recorded data is short of a unit data amount, the remaining portion of the unit data amount is filled with data of a special pattern.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
155 words
In a method of performing data compression of audio data and sequentially recording the data on a disk in units of data, each unit of data being formed of a predetermined amount of the data, said method of recording of a disk comprising the steps of: detecting a breakpoint of said audio data; continuously recording said audio data input temporally continuously, by joining, even at said breakpoint, said data preceding and subsequent to the breakpoint thereby forming said unit of data; recording a piece of information indicating the position of said breakpoint of said disk; and wherein, when an operation to suspend or stop the recording operation has been made, the last record data immediately before the suspension or stoppage of recording is included in said unit of data and recorded as a portion of said unit of data and the subsequent record data is started to be recorded with a new unit of data.
Claim 2
Dependent Claim
155 words
In a method of performing data compression of audio data and sequentially recording the data on a disk in units of data, each unit of data being formed of a predetermined amount of the data, said method of recording of a disk comprising the steps of: detecting a breakpoint of said audio data; continuously recording said audio data input temporally continuously, by joining, even at said breakpoint, said data preceding and subsequent to the breakpoint thereby forming said unit of data; recording a piece of information indicating the position of said breakpoint of said disk; and wherein, when an operation to suspend or stop the recording operation has been made, the last record data immediately before the suspension or stoppage of recording is included in said unit of data and recorded as a portion of said unit of data and the subsequent record data is started to be recorded with a new unit of data.
Claim 3
Dependent Claim
57 words
A method of recording a disk according to claim 1, wherein, when the last record data at the time when an operation to suspend or stop the recording operation has been made is short of the amount of said unit of data, the remaining portion of said last unit of data is filled with specific pattern data.
Claim 4
Dependent Claim
113 words
A method of recording a disk according to claim 1 wherein the disk has address information corresponding to a different recorded position on the disk of each breakpoint of the audio data recorded thereon, and comprising the further steps of: adjusting the position of the breakpoint by changing the address data; detecting whether or not the audio data preceding and subsequent to the breakpoint are recorded temporally continuously; and controlling the adjusting of the position of the breakpoint, when audio data preceding and subsequent to the breakpoint are detected to be temporally discontinuous, so that the changing of the address information in the direction of the data producing a temporal discontinuity becomes impossible.
Claim 5
Dependent Claim
49 words
A method of recording a disk according to claim 3, wherein the step of detecting a temporal discontinuity between the audio data preceding and subsequent to each breakpoint is carried out according to temporal information of each set of the data recorded on the disk separated by each breakpoint.
Claim 6
Dependent Claim
53 words
A method of recording a disk according to claim 3, wherein the step of detecting step temporal discontinuity between the audio data preceding and subsequent to the breakpoint is carried out according to information about record data recorded in an area other than the area recording the audio data therein of the disk.
Claim 7
Dependent Claim
135 words
In a method of performing data compression of audio data and sequentially recording the data on a disk in units of the data, each unit being formed of a predetermined amount of the data, the method of recording a disk comprising the steps of: continuously recording the audio data input temporally continuously; detecting a breakpoint of the audio data; recording a piece of information indicating the position of the breakpoint of the disk; and detecting when an operation to suspend or stop the recording operation has been made, and then including the last record data immediately before the suspension or stoppage of recording in the unit of data and recording the last record data as a portion of the unit of data and starting recording of subsequent record data with a new unit of data.
Claim 8
Dependent Claim
135 words
In a method of performing data compression of audio data and sequentially recording the data on a disk in units of the data, each unit being formed of a predetermined amount of the data, the method of recording a disk comprising the steps of: continuously recording the audio data input temporally continuously; detecting a breakpoint of the audio data; recording a piece of information indicating the position of the breakpoint of the disk; and detecting when an operation to suspend or stop the recording operation has been made, and then including the last record data immediately before the suspension or stoppage of recording in the unit of data and recording the last record data as a portion of the unit of data and starting recording of subsequent record data with a new unit of data.
Claim 9
Dependent Claim
58 words
A method of recording a disk according to claim 6, wherein, when the last record data at the time when an operation to suspend or stop the recording operation has been made is short of the amount of the unit of data, recording a specific pattern of data as the remaining portion of the last unit of data.
Claim 10
Dependent Claim
119 words
A method of recording a disk according to claim 7, wherein the disk has address information corresponding to a different recorded position on the disk of each breakpoint of the audio data recorded thereon, and further comprising the steps of: adjusting a cuing position of the audio data by changing the address information; detecting by means of the specific pattern data whether or not the audio data preceding and subsequent to the breakpoint are temporally continuously recorded; and controlling the adjustment of the cuing position, when audio data preceding and subsequent to the breakpoint are detected to be temporally discontinuous, so that changing of the address information in the direction of the data producing a temporal discontinuity becomes impossible.
