Abstract: A method preprograms a video cassette recorder (VCR) to record a desired television (TV) program. When a reservation key is pressed by the VCR's user for the preprogramming of the VCR, a preprogramming commencement signal is issued. In response to the preprogramming commencement signal, a recording start time, a recording channel and a recording tape speed are automatically set all at once. A recording end time is obtained by adding a predetermined duration of recording to the recording start time. The recording start time set and the recording end time are adjusted to an actual recording start time and an actual recording end time, respectively, through the use of an on touch screen manner.

Abstract: Thin film AMA is disclosed. The thin film AMA has an active matrix, a supporting member, an actuator, and a reflecting member. The actuator has a bottom electrode, two active layers, and two top electrodes. The actuator has maximum tilting angle due to margins formed between the bottom electrode and the two active layers or between the two active layers and the two top electrodes. Also, the tilting angle of the actuator is increased because the layers of the actuator respectively have proper thicknesses. Therefore, the quality of the picture projected onto a screen is enhanced and the arrangement of the AMA may be more easy.
