720602000 | Controlling acceleration, deceleration or speed | 7 |
20090265727 | DISC DEVICE - When a normal disk having the diameter of 12 cm is inserted into the disk device, first and second optical detecting elements detect the insertion, and transitions to a first detection state, which initiates transfer operation of first and second transfer rollers. If the disk is further moved to an inner portion of the device, thus pressing first and second detecting pins, first and second detecting switches are turned OFF, and the detecting elements enter a second detection state. Before the transition from the first detection state to the second detection state occurs, a rotating speed of the first and second transfer rollers is set low. After transition to the second detection state, the rotating speed is increased. As a result, a card or other such foreign objects can be removed and a monitoring period can be increased until detection of a normal disk is detected. | 10-22-2009 |
20100333119 | Tray Control Method for a Disk Drive - A tray control method for a disk drive including a tray for carrying a disk, a detect switch movable to different inclined positions for detecting different positions of the tray during tray ejection and retraction operation, a firmware for receiving signals transmitted by the detect switch upon reaching the different inclined positions so as to adjust a voltage applied to a DC motor and the speed for moving the tray to the different positions such that the tray moves stably when retracting into and ejecting from the disk drive. | 12-30-2010 |
20110265104 | OPTICAL DISC PLAYER - An optical disc player includes a case, a tray received in the case, and a decelerating member. The tray is adapted to hold an optical disc. The decelerating member integrates with the case, and is capable of stopping the rotating optical disc by friction generated between the decelerating member and edge of the rotating optical disc. | 10-27-2011 |
20140019999 | DISK DEVICE AND METHOD OF DRIVING TRAY OF DISK DEVICE - A disk device and a method of driving a tray of the disk device. The method includes outputting a tray driving control signal in response to a tray opening instruction, and maximizing an output voltage of the tray driving control signal during a time period in which the tray is expected to be stalled. | 01-16-2014 |
20140068640 | CD PLAYER AND METHOD FOR EJECTION CONTROL THEREOF - A compact disc (CD) player and method for ejection control thereof is provided. The CD player has: a CD tray, an eject button, a front-end module, a back-end module, and a fast response eject module, wherein the front-end module and the back-end module are coupled to each other and integrated in an integrated circuit (IC). The fast response eject module has a second tray control module for detecting a status of the eject button, and a second ejection detection module for controlling the ejecting/inserting of the CD tray according to the detected status of the eject button after the CD player is powered up and before initialization of the first ejection detection module is completed. Accordingly, the CD player of the invention may quickly respond to the status of the eject button and control ejecting/inserting of the CD tray immediately after the CD player is powered up. | 03-06-2014 |
20140115611 | TESTING DEVICE AND METHOD - A testing method tests a disc loading and transferring mechanism having a tray. The testing method includes steps of: transmitting a tray-out instruction and a tray-in instruction in that order to drive the tray to alternate between a closed position and a opened; counting a first period of the tray moving from the closed position to the opened position and a second period of the tray moving from the opened position to the closed position; determining whether the first counted period and the second counted period are in conformity with predetermined and expected standards, and outputting test results for indicating the disc loading and transferring mechanism is not in conformity with predetermined and expected standards when the first counted period and the second counted period are in conformity with predetermined and expected standards. | 04-24-2014 |
20150074691 | CD PLAYER AND METHOD FOR EJECTION CONTROL THEREOF - A compact disc (CD) player and method for ejection control thereof is provided. The CD player has: a CD tray, an eject button, a front-end module, a back-end module, and a fast response eject module, wherein the front-end module and the back-end module are coupled to each other and integrated in an integrated circuit (IC). The fast response eject module has a tray control module for detecting a status of the eject button, and an ejection detection module for controlling the ejecting/inserting of the CD tray according to the detected status of the eject button after the CD player is powered up and before the front-end module starts to work. The CD player of the invention may quickly respond to the status of the eject button and control ejecting/inserting of the CD tray immediately after the CD player is powered up. | 03-12-2015 |
