The present invention provides a method and a device for embedding event notification into multimedia content being reproduced on an electronic device. An original bandwidth count value of an input flow is received. The apparatus also includes a guide that guides each incoming item of media transported to the rotatable member. A cover may be attached to the base member for housing the first and second discs in an assembly compressible in response to a user rotatable control. In the technique of forming a silicide film formed of Ni and Si, where one or more chemical compounds represented with the following general formula I are used as an Ni source:where R1, R2, R3, R4, R5, R6, R7, R8, R9, or R10 is H or a hydrocarbon group.
