A magneto-resistive magnetic head with separate magnetic head structure

Abstract

The invention relates to the technical field of magnetoresistive heads, and discloses a magnetoresistive head with a separated magnetic head structure. The magnetoresistive head comprises a main rotating shaft. The outer side of the main rotating shaft is connected with a plurality of magnetic disks. The upper and lower surfaces of the disk are connected with a working magnetic head, the upper endof the working magnetic head is connected with a magnetic head arm, the other end of the magnetic head arm is connected with a magnetic head frame, the side of the working magnetic head is connectedwith a scraper, a gear is connected inside the scraper, the lower end of the gear is connected with a support, and the working magnetic head close to the disk is connected with an arc resistor. The magnetic head arm rotates a certain angle along with the magnetic head rotating shaft, and the metal ball on the magnetic head arm slides on the arc-shaped resistor. The driving device drives the gear to rotate by a certain angle, the driving gear is meshed with the tooth row, and the arc-shaped key is matched with the sliding groove to move relative to the working magnetic head, so that the workingmagnetic head is prevented from being scratched, and the working magnetic head is easy to collide in a critical area of a magnetic disk.

Description

technical field [0001] The invention relates to the technical field of magnetoresistive heads, in particular to a magnetoresistive head with a separate magnetic head structure. Background technique [0002] Magnetoresistive head technology MR is the abbreviation of magnetoresistive head. MR technology can increase the actual recording density and record data, thereby increasing the capacity of the hard disk and improving the data throughput rate. The working principle of the magnetoresistive magnetic head is based on the magnetoresistance effect. Its core is a small piece of metal material, and its resistance changes with the change of the magnetic field. Amplifier, so the small resistance change can be measured. MR technology can increase the hard disk capacity by more than 40%, thus greatly improving the throughput rate of the magnetoresistive head and reducing the volume of the hard disk. [0003] The magnetic head is used in conjunction with the magnetic scale to read...
