ABSTRACT:
Information carrier and recording device for recording an information carrier. The information carrier according to the invention is of an optically inscribable type, such as a CD-E or CD-WO. Information can be recorded as a track of patterns on the information carrier. The manufacturer has provided the information carrier with carrier information, for example, information about the write power to be used. It is desirable for the patterns to have constant dimensions, irrespective of the velocity at which they are recorded. The recording process in which for the recording is effected is therefore to be adapted to the recording velocity. In order to attune this adaptation to the information carrier, the latter contains velocity-related information indicative of the recording process related to a recording velocity, for example, a reference velocity (V1-V3), while the remaining recording parameters (W1-W3) are given for a minimum and/or maximum recording velocity at which the information carrier can be recorded. The device reads the velocity-related information from the information carrier and adapts the recording process to the recording velocity that must actually be used.
