Abstract
Data reading and writing apparatuses and data reading and writing methods are provided. In a data reading apparatus or a data writing apparatus, an optical head array including a plurality of laser heads is disposed, so that a quantity of laser heads for reading/writing data is increased. In addition, each laser head is improved, and a plurality of focal points are disposed in the laser head, so that in a data reading/writing process, parallel reading/writing of a plurality of pieces of data may be implemented by using the plurality of laser heads and the plurality of focal points in the laser head, and a data read/write throughput of an optical storage medium may be improved.
