An optical device has a holding frame that holds a liquid crystal panel as an optical modulator and has an opening at a part corresponding to an image formation area of the liquid crystal panel, and a panel fixing plate disposed between the holding frame and a cross dichroic prism. The frequency and phase discriminators may be used to periodically sample and estimate, respectively, the frequency and phase of an input analog signal, and these estimates are provided to a control network which calculates an error estimate and adjusts the estimate of the frequency provided by the frequency discriminator based on this estimate of the error. Two or more dispensing technologies can be combined to provide for increased efficiency in the dispensing of high volume liquid components. The BGA substrate is void of BGA solder balls between the designated high speed BGA solder ball and at least one edge of the substrate, thus providing a clear path to the designated high speed BGA solder ball for a high speed conductive trace formed on a printed circuit board. Accordingly, it is possible to record an information signal having a large amount of information in the recording medium without lowering a recording speed and it is also possible to easily reduce the size, weight and cost of the apparatus. This system utilizes a preauthored music sequence and a controller that listens to the SPDIF output of a DVD player.
