A light emitting module packaging two light sources emitting two light beams of different wavelengths, and a compatible optical pickup device adopting the module are provided. The light emitting module includes a base, first and second light sources installed on the base, for emitting laser beams in different wavelength regions, a beam splitter and a monitoring photodetector for monitoring the optical outputs of the first and second light sources by receiving the beams emitted from the first and second light sources and split from the beam splitter in one direction. Also, another light emitting module includes a substrate, first and second light sources installed on the substrate for emitting laser beams of first and second wavelengths from both lateral sides thereof, a reflection member for reflecting the laser beam emitted from one lateral side of each of the first and second light sources to proceed in one direction, and first and second monitoring photodetectors for monitoring optical outputs of the first and second light sources. The compatible optical pickup device includes the light emitting module having the above structure, an objective lens for focusing first and second laser beams on an optical recording medium, an optical path converting device, a grating arranged on an optical path between the light emitting module and the optical path converting device for diffracting and transmitting an incident light, a photodetector.

PROBLEM TO BE SOLVED: To provide a content creation apparatus and method that enable mail-order houses and the like to easily create content for a mobile site for cellular telephones and upload it to a server for providing the mobile site, with their own computer. SOLUTION: A content creation screen is displayed where it divides a module name display part, a mobile screen selection module name display part and a module content display part as screens. The module name display part lists basic module names and free module names for desired content creation, and some of them are selected and moved for display to the mobile screen selection module name display part, where they are arbitrarily rearranged, and are displayed or rewritten in the module content display part. Basic modules and free modules are combined into a single screen of content for a mobile site in the arrangement of such basic module names and free module names listed in the mobile screen selection module name display part.
