A method and a corresponding apparatus for recording an information on a recordable optical record carrier (2) by irradiation of a light beam through an optical system (3-7) onto said record carrier (2) for forming marks and lands representing said information along an information recording direction (t), obtains a higher recording density, and thus higher data capacity, by using astigmatism for influencing the light beam from the light source (8) to the record carrier (2) during recording of information so as 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 thereto, i.e., the radial direction.
A recording apparatus for recording information on a recordable optical record carrier by irradiation of a light beam onto said record carrier for forming marks and lands representing said information along an information recording direction, comprising:
A method of recording an information on a recordable optical record carrier by irradiation of a light beam through optical means onto said record carrier for forming marks and lands representing said information along an information recording direction, said method comprising the steps of:
