Rotary drum device and magnetic recording/reproducing apparatus having a more protruding inductive magnetic head relative to magnetoresistive head |
摘要 |
A rotary drum device and a helical scan magnetic recording/reproducing apparatus employing an MR head as a playback magnetic head. The rotary drum device and the helical scan magnetic recording/reproducing apparatus each include a cylindrically-shaped rotary drum, an inductive magnetic head loaded on the rotary drum so that its portion is protruded from the outer periphery of the rotary drum and a magneto-resistive effect magnetic head loaded on the rotary drum so that its portion is protruded from the outer periphery of the rotary drum. An amount of protrusion from the outer periphery of the rotary drum of the magneto-resistive effect magnetic head is smaller than an amount of protrusion from the outer periphery of the rotary drum of the inductive magnetic head.
