A HEAD DRUM ASSEMBLY AND A METHOD OF ASSEMBLING FOR THE SAME

摘要

A head drum assembly and an assemblage method therefor are provided to uniformly maintain an interval between a pair of transformers and be easily assembled and disassembled. A fixed drum(120) is fixed to a shaft(111). A rotary drum(130), rotatably combined to the shaft(111) to be faced with the fixed drum(120), has a magnetic head(132) and a rotary transformer(134). A cover drum(140), installed in the shaft(111) to be located in an upper part of the rotary drum(130), has a fixed transformer(141) which interacts with the rotary transformer(134). The cover drum(140) is fixed to the shaft(111) by a screw coupled to a screw groove(143) penetrated to a shaft side at its side.
