Embodiment Construction

[0050] see figure 1 , which illustrates a magneto-resistive type magnetic head according to the present invention. The magnetic head is generally indicated by reference numeral 1 . It includes: a substrate 2, a magnetic head element 3 formed on the substrate 2 by a thin film forming process, and another substrate 4 combined with the magnetic head element 3. as will be from figure 2 As seen, a magnetic head 1 is mounted on a drum 5 and reads a signal from a magnetic tape 6 by a helical scanning method.

[0051] like figure 1 As shown, the head element 3 is arranged at an angle (the so-called azimuth) that is not perpendicular to the tape feed direction A relative to the movement or feed direction of the magnetic tape 6 associated with the head 1 .

[0052] Both the base plates 2 and 4 are respectively formed as substantially rectangular thin plates, and their top end faces serve as sliding faces 2a and 4a, respectively. The tape sliding surfaces 2a and 4a are formed into ...

Abstract

Provided is a magneto-resistive type magnetic head having a magneto-resistive element sandwiched between a pair of shield plates of soft magnetic material to detect a magnetic tape signal by a magneto-resistive effect, the magneto-resistive element having a function perpendicular to a magnetic tape feed or The direction of the moving direction is a magnetic detection part arranged in an oblique manner with a predetermined azimuth angle. The magnetoresistive magnetic head is installed on the rotating drum to read signals from the magnetic tape by the helical scanning method. Also provided is a recording / reproducing device on which a rotary drum, a magnetoresistive type magnetic head as a read head, and an inductive type magnetic head as a write head are mounted, and a signal is read from or written to a magnetic tape by a helical scanning method .

Description

technical field [0001] The present invention relates to a magneto-resistive type magnetic head mounted on a rotary drum to read information from a magnetic tape as a recording medium by helical scanning, and a magnetic recording / reproducing apparatus using the magneto-resistive type head. Background technique [0002] The most common magnetic recording / reproducing apparatus using a magnetic tape as a recording medium include a video recorder, a tape recorder, a data storage system of a computer, and the like. It has been desired to increase the storage capacity of magnetic recording / reproducing devices by increasing the recording density. [0003] In order to meet the demand for high recording density and large storage capacity, it has been proposed to use a magnetoresistive type magnetic head (hereinafter referred to as "MR head") on a magnetic recording / reproducing device and much research has been conducted for practical use. [0004] A magnetoresistive element (hereinaf...
