Abstract: A provided computer system has a variety of additional application functions such as television, audio, video, communication, game, home automation functions, etc., as well as general mathematical computation and logic functions. Also, the system has a switch circuit and a booting control circuit. The switch circuit is used in selecting the additional functions which has a plurality of switches corresponding to the functions respectively. The booting control circuit is operated with a first supply voltage VCC.sub.-- A which allows power supply to apply a second supply voltage VCC.sub.-- B to central processing unit, several kinds of memory units and input/output peripherals when at least one of the switches is on. The central processing unit loads basic input/output system routines into random access memory so as to initialize and check circuits of the computer system, and loads application routines for the additional functions into the random access memory without loading operating system routines when the at least one of the switches is on.

Abstract: Disclosed is a rotary head drum for a VCR having an improved structure. A cylindrical lower drum and an upper drum installed on the lower drum and rotatably supported by the lower drum, are included. At least two video heads are provided at the outer lower portion of the upper drum for recording or playing a video signal onto or from a magnetic tape. Also, a lower rotary transducer is formed in an upper potion of the lower drum. An upper rotary transducer is positioned on the lower rotary transducer for transmitting an applied signal from the video head to the lower rotary transducer. A stator is positioned on the upper rotary transducer. The stator is transformed into an electromagnet according to an application of current. A ring-shaped magnet is provided in the upper drum at the same height as the stator. A circular magnet is formed above the stator and in the upper drum. Since the drum shaft insertion process is eliminated, the manufacturing of the head drum is advantageous. In addition, the noise generated during the operation of the head drum is reduced.
