Optical record carrier recording method, optical record carrier and apparatus for writing information

Abstract

Described is an optical record carrier recording method, optical record carrier (11) and an apparatus for writing information to an optical record carrier (11). The optical record carrier recording method forms pits and lands by controlling a radiation source to direct a radiation beam onto a recording surface of an optical record carrier (11), the method comprises the steps of: reading a write strategy from the optical record carrier (11) which comprises at least two write strategies, and forming the pits and lands by controlling the radiation source with the read write strategy, wherein themethod further comprises a step of determining which of the at least two write strategies is the most optimal one by reading an indication present on the optical record carrier (11), and wherein the method uses the most optimal write strategy to form the pits and the lands. If an apparatus for writing information to an optical record carrier (11) is capable of applying two or more write strategies stored on the optical record carrier, then the apparatus reads the indication and applies the write strategy which is the most optimal one.

Description

technical field [0001] The invention relates to a recording method for an optical record carrier by controlling a radiation source to direct a radiation beam onto a recording surface of an optical record carrier to form pits and lands. [0002] The invention further relates to an optical record carrier. [0003] The invention also relates to a device for writing information onto an optical record carrier. Background technique [0004] Optical media stores data in digital form, and it includes all of the various CD and DVD and Blu-ray disc technologies. Data stored on such media may include video, text, audio, computer data, or any other form of digital information. This data is written to and read from the disc using a laser beam. [0005] Various disc manufacturers exist. Thus many different formats and disc types are commercially available. Even in standardized disc formats such as CD-R, CD-R / W, DVD-R, DVD-R / W, BD+R, BD+R / W, each type of disc can have different materi...

AI Technical Summary

Problems solved by technology

However, if at least two write strategies are written to the optical record carrier and the device is able to use both write strategies, the device does not know which is the best for the optical record carrier

In case even more write strategies are stored on the optical record carrier, the choices will become more and it is more likely that the best write strategy cannot be chosen
