A recording apparatus and a recording method are provided. Control information is generated by the microcontroller based on the received command. The data preparing unit has a control register and a preparing circuit, wherein the control register is used for storing a set of control register values corresponding to the control information, and the preparing circuit is used for generating prepared data based on the set of control register values and storing the prepared data in the data buffer. The recording circuit records on an optical storage media based on the prepared data. The optical storage media has a lead-in area having a plurality of continuous zones. The prepared data includes a plurality of data to be written into the corresponding zones and the plurality of data are stored in the data buffer in the same sequence as the writing sequence to the zones and are read continuously.

Recording apparatus and recording method

A data recording method for an optical disk drive is implemented by the following steps. First, one or more data blocks are encoded and recorded sequentially, and it detects if a buffer under run occurs. If a buffer under run occurs, the recording does not stop immediately until at least the main data of the data block being currently recorded have been recorded completely. Afterwards, it restarts to encode and record from the data block next to the data block where the recording stops. Moreover, the recording also can stops if a servo error is detected, and the data restart to encode and record from the data block where the recording stops or at least one data block preceding the data block where the recording stops.

Data recording method for optical disk drive

A method for accessing a variable memory of an optical disk drive includes utilizing the optical disk drive to read and write data of an optical disk, and identifying the type of the data. If the data is CD data, arrange writing variables from a first initial address of the variable memory and reading variables from a second initial address of the variable memory. If the type of the data is DVD data, arrange writing variables from the first initial address of the variable memory and reading variables from the second initial address of the variable memory.

Method for accessing a variable memory of an optical disk drive

A drive controller is capable of reading information from an optically encoded disk. The drive controller is made to attempt a first read operation from a first area of the optically encoded disk to generate a first data set. If the first read operation is successful, the drive controller then verifies that the first data set conforms to a first data format. A media type descriptor is obtained from the first data set if the first data set conforms to the first data format. A media type descriptor is obtained from a second data set read from a second area of the optically encoded disk if the first data set does not conform to the first data format, or if the first read operation is not successful.
