摘要： Turntable runout of an optical disk drive is corrected by the application of at least three skidproof rubber pads affixed to the turntable on a circle and separated by equal angles. The height of each of the skidproof rubber pads is selected to adjust the runout of the turntable at each location. The invention accomplishes the compensation of turntable runout where, traditionally, lathe-turning was required.

摘要： A data reading method used in a reading device is provided. The reading device is for reading a hologram storage medium having a plurality of data pages, wherein each data page forms a data image having a plurality of image pixels on a sensing area of the reading device. The sensing area has a plurality of sensing pixels. The data reading method first determines a relative positional relationship between each image pixel and the sensing pixels or the optical quality of the corresponding data image of each image pixel. Next, a corresponding decoding unit of the sensing area is determined according to at least one of the relative positional relationship and the optical quality. Last, each image pixel is decoded by the corresponding decoding unit.

摘要： An optical disk drive has a lid an emergency ejection hole. An opening is defined in the lid. The emergency ejection structure comprises a locking element having a locking hook and an ejection lever, a safety element movably disposed under the emergency ejection hole, and an electromagnetic unit for generating magnetic field to attract the safety element in the optical disk drive. The locking hook is fitted the opening and keep the lid closed. With magnetic force, electromagnetic unit attracts the safety element. The locking hook can engage with the opening when the optical disk drive is connected to electrical power that enables the electromagnetic unit to attract and hold the safety element. The locking hook can disengage from the opening when the optical disk drive is disconnected from electrical power, enabling the electromagnetic unit to release the safety element.

摘要： A control method for ejecting optical disk from optical disk driver is proposed and applicable to both vertical type and horizontal type optical disk drivers. The control method firstly measures the minimal voltage require by the tray motor to eject a tray with or without an optical disk loaded thereon. Afterward, the disk loading condition of the tray is examined before the ejecting voltage is applied to the tray motor. The minimal voltage determined in above is applied to the tray motor according to the disk loading condition of the tray.

摘要： A data reading method used in a reading device for reading a holographic storage medium is provided. The holographic storage medium has several data areas. Each data area has several data pages, and each data page forms a data image that has at least one reserved block pattern on the reading device. The reserved block pattern of the data image corresponding to a first data page is searched within a first searching region to obtain a first pattern position. The reserved block pattern of the data image corresponding to a second data page is searched within a second searching region to obtain a second pattern position. A third searching position is then determined according to the first and second pattern positions. The reserved block pattern of the data image corresponding to a third data page is searched within a third searching region whose center is at the third searching position.
