为了证明磁带介质的最高面记录密度，我们开发了一种金属蒸发带，其具有较高的2.5倍的磁各向异性10<sup>5</sup>J/m<sup>3</sup>和较小的磁激活体积2.7倍10<sup>-24<sup>m</sup>m<sup>3</sup>的Co-CoO记录层沉积在更光滑的基膜上。使用巨磁阻头作为读取头确认了23.0 Gb/in的面记录密度的能力。更光滑的表面粗糙度使信噪比提高了2分贝以上
To demonstrate the highest areal recording density of tape media, we have developed a metal evaporated tape with higher magnetic anisotropy of 2.5times10<sup>5</sup> J/m<sup>3</sup> and finer magnetic activation volume of 2.7times10<sup>-24</sup> m<sup>3</sup> of a Co-CoO recording layer deposited on a smoother base film. A capability of an areal recording density of 23.0 Gb/in<sup>2</sup> was confirmed using a giant magnetoresistive head as a read head. The smoother surface roughness improved signal-to-noise ratio more than 2 dB
