Abstract: PURPOSE:To surely record a signal on a tape by recording the signal to be recorded with an azimuth head on a track as it is by means of a sub-azimuth head when the prescribed signal is not recorded with a main azimuth head. CONSTITUTION:The sub-azimuth heads 13 and 14 are provided which detect the signal recorded on the track by tracing the main azimuth heads 11 and 12 on the track where the signal is recorded by the main azimuth heads 11 and 12. Further, when it is judged that the prescribed signal is not recorded on the track from the signal detected by the sub-azimuth heads 13 and 14, the signal to be recorded by the main azimuth heads 11 and 12 is recorded on the track by means of the sub-azimuth heads 13 and 14. Thus, when the main azimuth heads 11 and 12 are defective at the time of the recording, the signal can be recorded on the tape by the sub-azimuth heads 13 and 14, and the signal can be surely recorded on a tape 3.

Abstract: PURPOSE:To protect a device from an increase in element resistance or in driving voltage or from undesirable changes in oscillation switching by a method wherein a first conductivity type boundary layer, provided with a second conductivity type region only in the vicinity of a stripe-geometry groove and consisting of an oxidation-resisting semiconductor, is built under a current-constricting layer. CONSTITUTION:Layers, a clad layer 2- current-constricting layer 6a, are grown on a substrate 1, after which etching is accomplished for the formation of a stripe-geometry groove 11. Next, a clad layer 7a and a contact layer 8 are formed, when Zn is diffused out of the clad layer 7a for the formation of a P-type inversion region 12 because Zn concentration in the clad layer 7a is not lower than 5X10<18>cm<-3> and the growth is to take place at approximately 800 deg.C. With the impurity concentration in the current-constricting layer 6a being not lower than 5X10<18>cm<-3>, there is little P-type inversion layer 12 formed in the current-constricting layer 6a. The P-type inversion layer 12 exists mostly in the boundary layer 5 wherein impurity concentration is relatively low. Metal electrodes 9 and 10 are next constructed for the completion of an element of this design.
