Abstract
In a head drum assembly and a tape drive having said head drum assembly, the head drum assembly comprises a fixed shaft secured to a lower stator; a rotor having a motor part, and provided with a magnetic head; an upper stator disposed at a distance in an axial direction with the rotor held and secure to said shaft; and rotary transformers individually provided between the rotor and the stator. Thereby, there is realized a small and high performance head drum assembly and a tape drive in which crosstalk between different transmission system is prevented, and which improved mounting accuracy of rotary transformations.

A head drum assembly comprising:
- a fixed shaft secured to a lower stator;
- a rotor having a motor part, and provided with a magnetic head;
- an upper stator disposed at a distance in an axial direction with said rotor held and secured to said shaft;
- and
- rotary transformers individually provided between said rotor and said stators.
A tape drive comprising a head drum assembly in which a rotor is provided with a magnetic head, and a magnetic tape is wound at a predetermined angle, a guide pin for drawing out a magnetic tape from a tape cassette and winding the drawn magnetic tape around said head drum assembly to form a predetermined tape pass, a reel bed for supporting a reel of the tape cassette, and a capstan shaft for traveling the magnetic tape in corporation with a pinch roller, wherein said head drum assembly comprises a lower stator, a shaft secured thereto, a rotor having a motor part and provided with a magnetic head, an upper stator disposed at a distance in an axial direction with said rotor held and secured to said shaft, and rotary transformers individually provided between said rotor and said stator.
