Abstract
First data is divided into second data and third data which are equal in data rate. The second data and the third data are fed to first and second recording heads respectively. The second data and the third data are simultaneously recorded on the first and second recording surfaces of the optical disc by the first and second recording heads respectively in a zoned constant linear velocity technique in which each of the first and second recording surfaces of the optical disc is divided into zones, and the zones of the first recording surface and the zones of the second recording surface are grouped into pairs each having a zone of the first recording surface and a zone of the second recording surface which are opposite to each other. In addition, the second data and the third data are simultaneously recorded on zones in a pair respectively while the first and second recording heads are moved in opposite directions respectively.
