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 CO.
Claims20
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 which generates 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 which generates converted address data in compliance with the second recording format from the first address data;
- and
- a first timing generation circuit which generates a timing for writing of data to the first disc medium based on the converted address data.
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 which decodes a signal read from the first recording medium and generates first address data in compliance with the first format;
- a converter connected to the first decoder which generates converted address data complying with the second format from the first address data;
- and
- a second decoder which decodes a signal read from the second recording medium and generating second address data complying with the second format.
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, 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;
- generating a timing for writing data to the recording medium based on the converted address data;
- and recording data to the recording medium in accordance with said timing.
