Abstract
A method comprising recording data related to a start-up procedure on at least one of a plurality of recording layers disposed on an optical record carrier for reading back the recorded data during subsequent start-ups, the selection of the at least one recording layer based on properties of the at least one recording layer is disclosed. The technique reduces the optical record carrier start-up time and is useful for DVD, HD-DVD and BD recorders and/or players.
Claims18
A method for recording data related to a start-up procedure on at least one of a plurality of recording layers disposed on an optical record carrier, the method comprising:
- selecting at least one recording layer based on one or more properties of the at least one recording layer, the properties of the at least one recording layer on which the selection is based including at least the repeated-read stability of recorded data as defined by a measurement of the repeated-read stability of recorded data;
- and
- recording the data related to the start-up procedure on the selected at least one recording layer for reading back the recorded data during subsequent start-ups.
A method for recording data related to a start-up procedure on at least one of a plurality of recording layers disposed on an optical record carrier, the method comprising:
- selecting at least one recording layer based on one or more properties of the at least one recording layer, the properties of the at least one recording layer on which the selection is based including at least one of measurement of the read stability and measurement of the read out speed of recorded data;
- and
- recording the data related to the start-up procedure on the selected at least one recording layer for reading back the recorded data during subsequent start-ups.
A drive for recording data related to a start-up procedure on at least one of a plurality of recording layers disposed on an optical record carrier, the drive comprising a control unit configured to:
- select at least one recording layer based on one or more properties of the at least one recording layer, the properties of the at least one recording layer on which the selection is based including at least the repeated-read stability of the recorded data as defined by a measurement of the repeated-read stability of recorded data, and
- record the data related to the start-up procedure on the selected at least one recording layer for reading back the recorded data during subsequent start-ups.
A drive for recording data related to a start-up procedure on at least one of a plurality of recording layers disposed on an optical record carrier, the drive comprising a control unit configured to:
- select at least one recording layer based on one or more properties of the at least one recording layer, the properties of the at least one recording layer on which the selection is based including at least the read out speed of the recorded data as defined by a measurement of the read out speed of recorded data;
- and
- record the data related to the start-up procedure on the selected at least one recording layer for reading back the recorded data during subsequent start-ups.
A non-transitory computer readable media comprising a computer program code configured to interact with a control unit of a drive for recording data on an optical record carrier, to perform a method for recording data related to a start-up procedure on at least one of a plurality of recording layers disposed on the optical record carrier, the method comprising:
- selecting at least one recording layer based on one or more properties of the at least one recording layer, the properties of the at least one recording layer on which the selection is based including at least the repeated-read stability of recorded data as defined by a measurement of the repeated-read stability of recorded data;
- and
- recording the data related to the start-up procedure on the selected at least one recording layer for reading back the recorded data during subsequent start-ups.
A non-transitory computer readable media comprising a computer program code configured to interact with a control unit of a drive for recording data on an optical record carrier, to perform a method for recording data related to a start-up procedure on at least one of a plurality of recording layers disposed on the optical record carrier, the method comprising:
- selecting at least one recording layer based on one or more properties of the at least one recording layer, the properties of the at least one recording layer on which the selection is based including at least the read out speed of recorded data as defined by a measurement of the read out speed of recorded data;
- and
- recording the data related to the start-up procedure on the selected at least one recording layer for reading back the recorded data during subsequent start-ups.
