ABSTRACT:
Disclosed is a head drum assembly for a VCR having a simple structure and high reliability. Provided is a shaft including a vertical groove extending from an upper portion to a lower portion of the shaft, a slanted groove extending from a lower end portion of the vertical groove to a maximum height that the shaft reaches, and a thrust cap inserted onto an upper end portion of the shaft by pressure. A lower drum is inserted into a lower end portion of the shaft by pressure and has a stator transfromer installed at the inner upper portion of the lower drum. An upper drum has at least two video heads installed at an outer bottom portion of the upper drum, and has a rotor transformer corresponding to the stator transformer at an inner bottom portion of the upper drum. A motor for imparting a driving force to the upper drum and for rotating the upper drum is provided. Bearing supporting effect can be obtained by using oil having low viscosity. Therefore, a consuming electric power can be reduced and a stable recording/reproduction can be achieved.
