Multiple label writes to an optical medium label surface are aligned with each other by reference to a calibration band disposed on the label surface. On initial insertion of the optical medium into the optical drive, a label alignment module uses the optical head to detect the calibration band or, if no calibration band exists, to write a calibration band. The label alignment module analyzes the eccentricity error presented by the calibration band during rotation of the optical medium, such as the amplitude and phase of the error, and applies the error to the optical head to write label information in alignment with the calibration band.

An optical disc apparatus may write information to an optical disc by forming a mark and a space on the optical disc. The optical disc apparatus may include a write stopping unit, a deviation calculating unit, and a write strategy correction unit.

The deviation calculating unit may obtain a deviation value of written information just before writing of information is stopped by the write stopping unit. The write strategy correcting unit may correct a write strategy based on the deviation and the previously-stored inherent variation. Writing of information to the optical disc may be restarted using the corrected write strategy.

A writing method for an optical disk drive includes the following steps. First, a write command and to-be-written data are received from a host. Next, a speed down flag is checked. If the speed down flag is true, a writing speed is decreased; or otherwise the to-be-written data is written into a data area. Next, the written data is read, and accuracy of the written data is verified. If the written data is not accurate, accurate data is re-written into a spare area, and the number of times of re-writing is counted and checked. If the number of times of re-writing is greater than a predetermined threshold value, the speed down flag is changed to true; or otherwise the procedure goes back to the data-writing step to repeat the above-mentioned steps. If the written data is read and verified as accurate, a write-end status is reported back to the host.
