Title: Head loading mechanism in magnetic recording device
Inventor: KUWATA NAOKI
IPC: G11B5/54
Filed: 1983-12-13
Abstract: PURPOSE:To supppress heat generation, reduce power consumption, and reduce magnetic effect on a magnetic medium by making head loading using a piezo- electric element in place of an electromagnet. CONSTITUTION:The head loading mechanism is provided with a magnetic head 21, a magnetic head suppout 22 and a magnetic head carriage 26 than support the magnetic head and a rotary fulcrum 25 that minutely rotates the magnetic head support 22 in a plane perpendicular to a magnetic medium 23. A piezo electric element 24 is provided between the magnetic head support 22 and magnetic head carrieage 26. By impressing voltage to the piezo-electric element, the element is expanded and contracted, and thereby the magnetic head support 22 is minutely rotated around the rotary fulcrum 25. Consequently, the magnetic head 21 is brought into close contact with the magnetic medium 23. Thus, by making head loading using a piezo-electric element instead of an electromagnet, heat generation is supporessed, power consumption is reduced and magnetic effect on the magnetic medium can be lessened.
