Abstract
In a recordable optical disc including at least one recording layer, write strategy information is recorded within disc control information, so that standardized disc control information can be uniformly applied to data recording and reproduction. At least one disc information is recorded as the disc control information within the management area. The disc control informations are recorded for at least one write strategy for a same writing speed and recording layer.
Claims26
A data structure of a control information for use with a recording medium having at least one recording layer, wherein the control information includes at least two information units including first information unit for a lower writing speed and second information unit for a higher writing speed, wherein the first information unit includes write strategy parameters for first write strategy type to be used for the writing speed, the first write strategy type being one of a plurality of write strategy types applicable to the same writing speed and recording layer, and the second information unit for a higher writing speed includes write strategy parameters for the first write strategy type or a second write strategy type to be used for the higher writing speed.
A recording method comprising:
- reading a control information from a specific area of a recording medium, the control information including at least two information units including first information unit for a lower writing speed and second information unit for a higher writing speed, wherein the first information unit includes write strategy parameters for first write strategy type to be used for the writing speed, the first write strategy type being one of a plurality of write strategy types applicable to the same writing speed and recording layer, and the second information unit for a higher writing speed includes write strategy parameters for the first write strategy type or a second write strategy type to be used for the higher writing speed;
- and
- recording data at a specific writing speed based on at least one information unit.
An apparatus for recording data, comprising:
- a pickup unit reading a control information from a specific area of a recording medium, the control information including at least two information units including first information unit for a lower writing speed and second information unit for a higher writing speed, wherein the first information unit includes write strategy parameters for first write strategy type to be used for the writing speed, the first write strategy type being one of a plurality of write strategy types applicable to the same writing speed and recording layer, and the second information unit for a higher writing speed includes write strategy parameters for the first write strategy type or a second write strategy type to be used for the higher writing speed;
- and
- a controller controlling the pickup unit to record data at a specific writing speed based on at least one information unit.
