摘要

在比特模式媒体记录(BPMR)技术中，数据存储在磁岛上。因此，为了增加面密度(AD)，我们必须减小磁岛之间的距离。这使得岛屿受到邻近岛屿的影响，即二维(2D)符号间干扰(ISI)，即分别来自交叉和下行方向的符号间干扰(ISI)和航迹间干扰(ITI)。

Iterative parallel-serial detection structure using MAP algorithm for bit-patterned media recording systems

In bit patterned media recording (BPMR) technology, data are stored on the magnetic islands. Thus, for increasing the areal density (AD), we have to reduce the distance between magnetic islands. This makes the islands be influenced by the neighboring islands, which is the two-dimensional (2D) inter-symbol interference (ISI), i.e. the inter-symbol interference (ISI) and inter-track interference (ITI) from the cross-and down-track directions, respectively.
