离散轨道记录技术在减少相邻轨道擦除/干扰方面提供了潜在的优势。随着纳米压印技术的进步，这种介质的制造已经被证明是可行的。近年来，离散径迹记录被普遍认为是下一步提高面密度的技术之一。在本研究中，我们评估了具有图案化轨道的PMR介质的记录性能。为了准确评估离散磁道性能的优势，并与当前的连续介质进行比较，在一个磁道上测量了这两种记录性能。在图案化的和连续的介质区域上监测头部飞行高度。在100 nm数据磁道宽度下，与相同磁道宽度下的连续介质相比，图案化磁道显示出显著更好的信噪比和显著降低的相邻磁道擦除。这些可测量的性能优势对于将磁道密度提高到300-400 KTPI以上至关重要
Discrete track recording technology offers a potential advantage in reducing adjacent track erasure/interference. As nano-imprinting technology advances, fabrication of such media has been demonstrated. In recent years, discrete track recording has generally been viewed as one of the next promising technologies for areal density advancement. In this study, we evaluated the recording performance of PMR media with patterned tracks. To accurately assess the advantage of discrete track performance and compare with current continuous media, both recording performances were measured on one single track. The head flying height is monitored on the patterned and continuous media regions. At 100-nm data track width, patterned tracks show noticeably better signal-to-noise ratio and significantly lower adjacent track erasure compared with continuous media at the same track width. Such measured performance advantages are critical to increase track density beyond 300-400 ktpi
