摘要： There is provided an optical storage device that can position a lens carriage and objective lens even when position sensors for the lens carriage and objective lens are excluded in an effort to make an optical disk unit thinner. When a seek of the carriage relative to an optical disk is started, the carriage is accelerated smoothly, decelerated smoothly, and thus positioned on a target track. The vibration of a lens actuator on the carriage occurring during seek can be minimized, and the lens actuator is locked substantially in the center of the carriage. During a seek operation of the carriage, a false lens signal equivalent to a lens signal used to lock the lens actuator in the center of the carriage is produced using the envelope of a tracking error signal obtained from reflected light of the light beam emanating from the optical disk. With the false lens signal, the lens actuator is locked in the center of the carriage.

摘要： Functions regarding a mechanical structure are made common so as to enable both of a CD and an MO cartridge to be used by one apparatus. When the CD as an exposed medium is loaded, the apparatus operates as a CD player. When the MO cartridge as a cartridge enclosed medium is loaded, the apparatus operates as an optical disk drive.

摘要： There is provided an optical storage device that can position a lens carriage and objective lens even when position sensors for the lens carriage and objective lens are excluded in an effort to make an optical disk unit thinner. In an optical storage device according to the first aspect of the present invention, when a seek of the carriage relative to an optical disk is started, the carriage is accelerated smoothly, decelerated smoothly, and thus positioned on a target track. The vibration of a lens actuator on the carriage occurring during seek can be minimized, and the lens actuator is locked substantially in the center of the carriage. According to the second aspect, during a seek operation of the carriage, a false lens signal equivalent to a lens signal used to lock the lens actuator in the center of the carriage is produced using the envelope of a tracking error signal obtained from reflected light of the light beam emanating from the optical disk. With the false lens signal, the lens actuator is locked in the center of the carriage.

摘要： A control method and controller for an optical storage drive including: an optical head having a laser light source for applying light to an optical disk and a detector for receiving reflected light from the optical disk; and a seek mechanism for positioning the optical head on the optical disk. The control method includes: measuring a drive current value with which the laser light source provides a predetermined light power value by an emission adjustment; writing the measured drive current value into a non-volatile memory as an initial value; adjusting the emission of the laser light source so that it provides the predetermined light power value; and comparing the drive current value with which the emission adjustment has been made with the initial value stored in the non-volatile memory. Also disclosed is a control method which measures and stores a write power value providing optimum write performance in a non volatile memory for controlling the power of the laser light source with the measured value.
