Abstract

A data recording apparatus recording data of a CD on an HDD in a manner such that the content of record in the CD is faithfully accounted for and shortening an operation time for a synchronized ripping operation. When the data recording apparatus reads, from the CD, track data managed by track, according to TOC, and records the track data onto the HDD, the data recording apparatus recognizes data unrecorded on the HDD, from among the track data recorded on the CD. This recognition process is automatically performed based on the TOC read from the CD, and album information replayed using the TOC and held by the HDD. The recording apparatus reproduces and outputs only the unrecorded data from the CD based on the recognition result concerning the unrecorded data. In this way, the data already recorded on the HDD is not transferred from the CD to the HDD. The operation time for the synchronized ripping operation is reduced accordingly.

Claims

1. A data recording apparatus comprising:

data reading means for reading data from a first recording medium that stores data and first management data for managing the data by track,

data recording means for recording data on a second recording medium,

management data producing means that produces second management data for managing data recorded on the second recording medium based on the first management data of the first recording medium on which the data recorded on the second recording medium has been recorded,

data determining means that determines data unrecorded on the second recording medium by comparing the first management data read by the data reading means from the first recording medium with the second management data recorded on the second recording medium, and

control means that reads the data determined by the data determining means from the first recording medium and causes the recording means to record the read data onto the second recording medium.

2. A data recording apparatus according to claim 1, wherein the first management data is a data number indicating data recorded on the first recording medium.

3. A data recording apparatus according to claim 1, further comprising display means that displays recording status of data, managed by the first management data read by the reading means from the first recording medium, on the second recording medium.

4. A data recording apparatus according to claim 1, further comprising data compressing means that compresses data read by the data reading means,

wherein the control means reads the data, determined by the data determining means, from the first recording medium, compresses the read data using the compressing means, and then causes the recording means to record the compressed data onto the second recording medium.

5. A data recording apparatus according to claim 4, wherein the compressing means compresses the data, read by the data reading means, at a predetermined compression ratio,

the management data producing means produces the second management data with data recorded on the second recording medium associated with data representing the compression ratio of the data recorded on the second recording medium,

the data determining means determines the data unrecorded on the second recording medium by comparing the first management data for managing the data recorded on the first recording medium with the second management data recorded on the second recording medium and the data representing the compression ratio, at which the compressing means compresses the data recorded on the first recording medium, and

the control means reads the data, determined by the data determining means, from the first recording medium, and causes the recording means to record the read data onto the second recording medium.

6. A data recording apparatus according to claim 1, comprising:

receiving means that receives data from a first recording medium that stores data and first management data for managing the data,

data recording means that store data, received by the receiving means, on a second recording medium,

management data producing means that produces second management data for managing data recorded on the second recording medium based on the first management data of the first recording medium on which the data recorded on the second recording medium has been recorded,

data determining means that determines data unrecorded on the second recording medium by comparing the first management data received by the receiving mean with the second management data recorded on the second recording medium, and

control means that causes the receiving means to receive the data determined by the data determining means, and causes the recording means to record the received data onto the second recording medium.

7. A data recording apparatus comprising:

data reading means for reading data from a first recording medium that stores programs and first management data for managing said programs,

data recording means for recording said programs and second management data on a second recording medium,

management data producing means for producing said second management data for managing said programs recorded on said second recording medium based on said first management data of said first recording medium,

data determining means for determining unrecorded programs on said second recording medium by comparing said first management data read by said data reading means from said first recording medium with said second management data recorded on said second recording medium, and

control means for controlling said data reading means to read said unrecorded programs among a plurality of programs from said first recording medium based on a result of comparison by said data determining means, and for controlling said recording means to record said unrecorded programs onto said second recording medium.

8. A data recording apparatus according to claim 7, wherein said first management data is a program number indicating data recorded on said first recording medium.

9. A data recording apparatus according to claim 7, further comprising display means for displaying recording progress status of programs.

10. A data recording apparatus according to claim 7, further comprising data compressing means for compressing said program read by said data reading means,

wherein said control means:

reads said program, determined by said data determining means, from said first recording medium,

compresses said read program using said compressing means, and then causes said recording means to record said compressed data onto said second recording medium.

11. A data recording apparatus according to claim 10, wherein said compressing means compresses said program, read by said data reading means, at a predetermined compression ratio,

said management data producing means produces said second management data with data recorded on said second recording medium associated including data representing said compression ratio of said program recorded on said second recording medium,

said data determining means determines a program as an unrecorded program when the program is determined as recorded program based on said first management data and said second management data but said predetermined compression ratio and said data representing the compression ratio of the program recorded on said second recording medium are different.
