摘要:
A method for improving readability of an optical disc includes: changing a first control parameter of an optical storage apparatus that accesses the optical disc and obtaining a plurality of associated values of an index corresponding to the readability of the optical disc for respective changed/unchanged values of the first control parameter; setting the first control parameter to be an optimal value out of the changed/unchanged values of the first control parameter according to the index; changing a second control parameter with the first parameter set to be the optimal value to obtaining a plurality of associated values of the index for respective changed/unchanged values of the second control parameter; and setting the second control parameter to be an optimal value according to the index. The control parameters having their individual optimal values are utilized for further control during decoding. In addition, an associated optical storage apparatus is further provided.

A method of processing a readback signal generated from reading an optical storage medium is provided. The method includes: performing a defect detection according to the readback signal to generate a defect detection result indicating defective areas on the optical storage medium; and performing a parameter calibration upon at least a parameter associated with processing of the readback signal according to the defect detection result.
摘要:
A method of recording data on a storage medium is provided. A first recording indicator is written on the storage medium to indicate a first state of a data recording thereon. A second recording indicator is written on the storage medium to indicate a second state of the data recording thereon. A recording status of the data recording is determined accordingly in accordance with the first and second indicators.
