  • Abstract
    It is well known that reducing the inductance of the HGA is useful to improve recording properties at a high frequency. We reduce the inductance of slider on the HGA by using a short yoke length writer made of only NiFe. The writer with narrow track width of 0.50 μm recorded at 350 MHz and 372 kfci
