HDD TuMR thin-film heads

Alps announced the development of its new HRUHM Series of 170Gbit/inch2 high-density recording hard disk drive (HDD) Tunneling Magneto Resistive (TuMR) thin-film heads.

The company explained that its TuMR element is a structure consisting of an insulating layer sandwiched between highly magnetic layers that when applied with a magnetic field, exhibits a tunnel effect in which an electric signal runs through the insulating body. The thickness of the TuMR element insulation layer is only a few nanometers, added Alps, making it a thin, low resistance and stable film.

According to the press release, Alps was able to realize a low resistance TuMR element by utilizing materials technology accumulated through its magnetic recorder business as well as process engineering deeply cultivated through the development and production of MR and GMR heads. The press release further said that the company realized even higher recording density for the recording surface of the write head through the use of the vertical recording system that is proven to boost recording density, and by shifting from the previous longitudinal system to the perpendicular system.

Full-scale mass-production is scheduled to begin in the first half of 2006. The HRUHM Series will be on display for three days beginning May 24, 2006 at the Alps Show 2006 to be held in the New Takanawa Prince Hotel in Minato-ku, Tokyo.
