Abstract: Disclosed is a transparent electrode film for a touch screen, which includes a transparent substrate, an assistant adhesive layer formed on each of both surfaces of the transparent substrate, and a transparent conductive polymer layer formed on the assistant adhesive layer, thus obviating a need for an optically clear adhesive film and resulting in increased transmittance and superior price competitiveness. A method of manufacturing the transparent electrode film is also provided.

Abstract: Disclosed herewith is a method of compensating for the seek errors of a pickup assembly. The method includes the steps of calculating a target track number to read data stored in an optical disc by transferring a pickup assembly across the optical disc; determining whether a seek error has to be compensated for in a radially outward direction of the optical disc; if the seek error has to be compensated for in a radially inward direction, compensating for the seek error; transferring the pickup assembly in the radially inward direction, reading an address of a current position of the pickup assembly, and determining whether the current position of the pickup assembly coincides with a target position; if the current position of the pickup assembly coincides with the target position, calculating the seek error in a radially inward direction and calculating an error compensation value in a radially inward direction; and storing the calculated error compensation value and using it to perform a next seek operation.

Abstract: A slot with a modified case to accommodate various types of flash memory cards having different sizes is disclosed. The slot includes a slot case divided into upper and lower spaces, and having an insert hole at its front face, a door being opened when the flash memory card is inserted into the insert hole, an elastic element for biasing the door to be closed, first insert guide faces for directing the flash memory card into the lower space, second insert guide faces positioned behind the first insert guide faces to guide the flash memory card passed over the first insert guide faces, slide faces for directing the flash memory card into the upper space, a plurality of insert guides into which the flash memory card inserted along the first and second insert guide faces and the slide faces are fitted, and a plurality of electrodes including contacts corresponding to pins of the flash memory card fitted in the plurality of insert guides.
