Abstract: A control mechanism for a clamper guider in a slot-in drive comprises a motor used to drive a transmission sheet to move through a gear train; the transmission sheet drives a control sheet to rotate counterclockwise or clockwise and further to cause a raised piece of the control sheet to prop against or separate from the lower end of a downward bended section of the clamper guider to allow a clamper at the lower section of the clamper guider to be separated from or entered the location that a disc is clamped. Whereby, the whole control mechanism has a more power saving structure and the matching design of the whole transmission structure and the motor used therein is more convenient.

Abstract: A clamper guider in a slot-in drive comprises a sheet body, a lower section at the lower side of the sheet body is disposed at the front end of the sheet body; a rear section pivotally connected to a ceiling plate of a chassis is disposed at the rear end of the sheet body; an arm is extended at the flank side of the sheet body, the flank side of the arm is connected to the ceiling plate of the chassis; a round hole combined with said clamper is disposed at the lower section. Whereby, the clamper guider has a smaller volume and the matching design of each component in the whole chassis is more convenient. And, a shorter pivoting end is disposed between the clamper guider and the ceiling plate of the chassis and the end that the clamper guider is combined with the clamper is more stable rather not to yield a shaking in the level direction.

Abstract: A transmission mechanism in a slot-in drive comprises a chassis respectively connected to a motor, worm, worm gear and a plurality of spur gears, a rubber roller, transmission sheet and control sheet, in which one of the spur gears and the rubber roller are connected to a same rotating shaft and can be driven by the adjacent spur gear; another spur gear can drive a rack of the transmission sheet to allow the transmission sheet to drive the control sheet to move; fewer components are installed in the whole structure, the assembly and the manufacturing are easier and the production cost can be reduced.

Abstract: A structure for combining a printing circuit board with a rack comprises a fixing sheet, a plurality of supporting seats and buckling sheet; the fixing sheet and the buckling sheet are respectively at the opposite sides; the fixing sheet has a level section, a positioning pin is disposed at the lower side of the level section; another pin is disposed at the top end of the supporting seat proximate to the buckling sheet; a buckling tenon is disposed on the top end of said buckling sheet; the fixing sheet, the supporting seats and the buckling sheet are used to fix the printing circuit board without needing other screws and screw drivers, the printing circuit board can then be allowed to combine with or separate from the rack. Whereby, the combination or the detaching operation can be more convenient, the production time and cost can be saved.

Abstract: An anti-shock traverse structure includes a movable frame attached to a traverse. The movable frame has elastic plates extending therefrom. The elastic plates have respective upwardly bent sections to resiliently bias against a lower side of a tray.

Abstract: A method and a device for controlling data transmission between IDE apparatuses allow an IDE controller of an IDE control device to send read control signal to an IDE apparatus via a set of IDE interfaces and a signal control transmission line and then to send write control signal to another IDE apparatus via another set of IDE interfaces and another signal control transmission line. Thus, the output data from the IDE apparatus through the data transmission line can be accelerated the transmission speed thereof between IDE apparatuses so as to save the time for transmitting data.

Abstract: An interface controller mounted in a SCSI hole includes a circuit board and a panel. The circuit board is associated with a chip, an IDE interface male plug and control circuit. The panel is disposed at a lateral side of the circuit board and has a size adapted to the SCSI hole and being joined to an inner side of the SCSI hole. The panel is associated with an inserted recess so as to be fixed to a used casing of an independent CD-ROM drive or hard disk drive with SCSI socket for saving production cost.

Abstract: An IDE connector with opposite male plug and female socket includes a circuit board with a control circuit, a chip, a male plug and a female socket. The male plug is joined to one side of the circuit and the female socket is joined to another side of the circuit board so as to be disposed oppositely. The female socket is connected to the male plug of an IDE device to enhance the data transmission quality between two IDE devices and decrease using of the flexible flat cable.

Abstract: A method for video data can process the backup a VCD with damage zones to overcome a deficiency of the conventional CD-RW drive being incapable of backing up a VCD with damage zones. The method is to read data saved in a directory zone of the data storage zone first and, then, confirm location of the damage zone. Next, the method allows the optical pickup to skip the damage zone during the process of backing up the data in the data storage zone so as to complete the backup job for the entire data storage zone without accessing the damage zone.

Abstract: A base seat for a sled motor, which can lower the height of the sled motor beyond a flat body of the traverse so as to reduce the gross thickness of a CD-ROM driver and to be favorable for design work, has a downward recessing joining surface for engaging with the sled motor. The joining surface at two lateral sides thereof extends a connecting plate to connect with the flat body of the traverse. The flat body has a downward bent reinforced rib close to the outer side of the joining surface. The joining surface at a lateral side thereof extends a projection plate to be associated with one of the transmission gears.
