Audio/control head and method assembling cores of the head

摘要

An audio/control head for used in a Video Cassette Recorder or the like has a core holder 11 arranged to include positioning portions 24 and 25 for determining the pitch length P1 and pressing tabs 23 having an elasticity for pressing inwardly cores members 15 and 17 against the positioning portions 24 and 25 from the outer side. As the cores members 15 and 17 are held directly on the positioning portions 24 and 25, they are inwardly pressed by the pressing tabs 23. Then, the core pitch p1 is precisely determined between the audio core and the control core without using particular jig during the assembly. The overall number of jigs required for mounting the cores to the core holder cab be reduced. Also, the core pitch P1 can be improved in the accuracy and the characteristics of the head will be consistent.
