摘要 |
The present invention relates to a method and a corresponding apparatus for recording an information on a recordable optical record carrier ( 2 ) by irradiation of a light beam through optical means ( 3 - 7 ) onto said record carrier ( 2 ) for forming marks and lands representing said information along an information recording direction (t). To obtain a higher recording density, and thus higher data capacity, it is proposed according to the present invention to reduce the numerical aperture of the optical means ( 3 - 7 ) in the direction (r) orthogonal to the information recording direction (t), which is the radial direction for an optical disc, during recording of information to obtain a light beam having a substantially oval spot profile having a shorter axis in the information recording direction (t), i.e. the tangential direction for an optical disc, compared to the direction (r) orthogonal that to, i.e. the radial direction.
