Abstract: PURPOSE:To eliminate a guard band by recording two video signals of one image on two nearest odd-numbered or even-numbered tracks, and setting azimuth angles differently on the odd-th and even-th tracks. CONSTITUTION:Lower cores 9 and 10 and upper cores 11 and 12 for channel, and channel gaps 13 and 14 are provided on the substrate 8 of a head 2. The track width of the channel gaps are set at the same dimension (a), and gap intervals at (b), and the dimension (b) is set slightly narrower than the (a).

Abstract: PROBLEM TO BE SOLVED: To prevent the failure of an optical fiber which occurs during use by constituting a semiconductor module so as to prevent the bringing the edge of an Si sub-mount and the optical fiber into contact with each other at the opening end of a V-groove. SOLUTION: At the time of wet etching the Si sub-mount 2 by using an etchant, such as potassium hydroxide, the Si sub-mount 2 is overetched more increasingly nearer the opening end 10 of the V-groove 11, by which the V- groove 11 is formed.
