20080253243 | Controlling an Optical Disc Drive - The invention provides an optical disc drive and a method for controlling a moving part, e.g. a disc tray or an optical pick-up unit, of such an optical disc drive. The method comprises, upon a start-up command being received, reading a reliability register, e.g. one bit, indicating whether stored data relating to the position of the moving part are reliable. In case the reliability register indicates that that stored data relating to the position of the moving part are un-reliable, then a blind homing is performed, and data relating to the position of the moving part are then stored in a memory. Preferably, a controlled homing action is performed after receipt of a stop command. An optical disc drive according the invention comprises a moving part (MP), a motor (MTR), e.g. a stepping motor, for driving the moving part (MP), a memory (MEM) for storing data relating to the position of the moving part (MP), a reliability register (REL_reg) for storing whether the data relating to the position of the moving part (MP) are reliable, and adjusting means (ADJ) for reading the memory (MEM) and adjusting settings of the motor (MTR), e.g. motor angle, according to the data read from the memory (MEM) in case the reliability register (REL_reg) indicates that data are reliable. The reliability register enables the best possible utilization of the stored position relevant data for adjusting settings of the motor driving the moving part of the optical disc drive. According to a preferred algorithm with proper use of the reliability register, blind homing actions can be minimized or completely eliminated during normal use of the optical disc drive, and still the disc drive will be able to function properly. | 2008-10-16 |
