    摘要： A method of mounting an optical device having a step on the surface opposing to a mounting substrate favorably by face-down bonding which enables a decrease in the number of components or integrate additional components on one identical substrate and, accordingly, is useful for reducing the size and the thickness of an optical head using a light source, the method includes the step of making the volume of a solder pattern to the area ratio of each electrode different for every wiring electrode portions upon mounting the electrodes on the substrate for mounting the optical device, in which the optical device having the step can be mounted favorably to the substrate by the control for the height of solder upon melting.

    摘要： A conventional problem is to provide an optical module capable of being reflow mounted together with electronic components collectively, and, at the same time, securing a mechanical strength that can bear a large stress at the time of an attachment/detachment of the optical fiber. A solution to the above-mentioned problem can be attained by using an optical connector removable type optical module for reflow mounting having a fixing structure for fixing itself to a mount board, including a receptacle part installed to an optical module 19 to which an optical connector 1 is detachably connected; electric terminals 4 for reflow mounting that are arranged corresponding to lands 8 on a mount board 6; and stud parts 5 that are able to fit in fixing holes 7 on the mount board 6.

    摘要： An information recording medium includes an information recording layer on which at least information is to be recorded by irradiating light, and a light transmission restricting layer which has a plurality of nonlinear transmission characteristics or nonlinear reflection characteristics for the intensity of the light irradiated and which has an optical material for restricting the transmission or reflection of the light according to the respective characteristics when the light is irradiated onto the information recording layer. An information recording and reproducing unit uses the information recording medium and includes an information recording position setting unit for deciding a position at which information is to be recorded on the information recording medium by detecting a direction of an easy magnetization axis. With the above arrangement, the spot diameter of the light can be distinguished between the one when information is reproduced and the one when information is recorded on the information recording medium respectively, to thereby ensure an accurate positioning of the head on the tracks of the recording medium.
