Abstract
A controller for recording data on a CD with a DVD recorder. The controller includes an LPP decoder, an ATIP decoder for decoding address information of a CD, and an address converter for converting an ATIP address into an LPP address. When recording DVD format data on a CD, a write timing generation circuit is driven in response to the LPP address, which is converted from the ATIP address. The write data is modulated for use in the CD, and the intensity of the write data is adjusted for use in the CD.
Claims18
A data recording controller for controlling recording of data to a first disc medium on which first address information is recorded in compliance with a first recording format, in compliance with a second recording format that has a recording density greater than the first recording format, the data recording controller comprising:
- a first address generation circuit for generating first address data based on the first address information read from the first disc medium;
- a conversion circuit, connected to the first address generation circuit, for converting the first address data to generate converted address data complying with the second recording format;
- a second address generation circuit for generating second address data complying with the second recording format based on second address information read from a second disc medium and complying with the second recording format;
- an address selection circuit, connected to the second address generation circuit and the conversion circuit, for selecting and outputting one of the second address data generated by the second address generation circuit, and the converted address data;
- and
- a first timing generation circuit, connected to the address selection circuit, for generating a timing for writing of data to the first disc medium in accordance with said one of the second address data and the converted address data selected by the address selection circuit.
A data recording controller for recording data to a first recording medium on which first address information complying with a first recording format is recorded, in compliance with a second recording format corresponding to a second recording medium, having a recording density that is greater than the first recording medium, the data recording controller comprising:
- a first decoder for decoding a signal read from the first recording medium and generating first address data complying with the first format;
- a converter, connected to the first decoder, for converting the first address data to generate converted address data complying with the second format;
- a second decoder for decoding second address information read from the second recording medium and generating second address data complying with the second format;
- and
- an address selection circuit, connected to the second decoder and the converter, for selecting and outputting one of the second address data and the converted address data.
A method for controlling recording of data to a recording medium on which first address information is recorded complying with a first recording format, in compliance with a second recording format that has a recording density greater than the first recording format, and wherein second address information is recorded on another recording medium, the method comprising:
- reading first address information from the recording medium;
- generating first address data based on first address information read from the recording medium;
- converting the first address data into converted address data complying with the second recording format:
- reading second address information from the another recording medium;
- generating second address data complying with the second recording format based on and in compliance with the second address information read from the another recording medium;
- selecting and outputting one of the second address data and the converted address data;
- generating a timing for writing data to the recording medium based on said selected one of the second address data and the converted address data;
- and
- recording data to the recording medium in accordance with said timing.
