Problems solved by technology

A problem with such known information carriers and devices is that when the information carrier is recorded at a speed deviating from the nominal recording speed, the recorded pattern may also deviate from the pattern recorded at the nominal recording speed

Embodiment Construction

[0015] In the drawings, elements corresponding to elements already described are denoted by the same reference signs.

[0016] FIG. 1 a shows a disc-shaped information carrier 1 having successive tracks 9 for recording, which are arranged in a circular spiral or, instead of a spiral, in concentric circles. The track 9 on the information carrier is represented by a servo pattern, in which for example a pre-groove portion 4 follows the track 9 with a read / write head during scanning. Servo patterns may be, for example, alternately uniformly distributed sub-patterns which periodically cause information to appear in a servo tracking system. Figure 1b shows a section along the line b-b of an information carrier 1 with a substrate 5 covered with a pick-up layer 6 and a transparent layer 7 . The pre-groove portion 4 may also be formed as a raised portion, or be formed with properties different from its surrounding material, and the pickup layer 6 may be written optically or magneto-o...

Abstract

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 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.

Description

[0001] This application is a divisional application of the Chinese application with the application number 96191532.3 and the title of the invention "Information Carrier and Recording Device for Recording Information Carrier". technical field [0002] The present invention relates to an inscribable type information carrier, which contains recording information indicating the recording process through which the information is recorded on the information carrier, and the recording information includes recording parameters of the recording process. [0003] The invention also relates to a device for recording an information carrier of the recordable type, the information carrier containing recording information indicating the recording process through which the information is recorded on the information carrier, the recording information including the record of the recording process parameters, the device comprises reading means for reading the recorded information and recording m...
