二维磁记录系统被广泛研究以实现更高的记录密度。由于记录密度非常高，微小的物理缺陷可能会导致许多二维错误。因此，磁记录系统的许多二维信号处理也被提出和研究。抹茶等人。提出了二维LDPC码并研究了该码的纠错性能。在本文中，我们提出了一种代码，它是他们代码的变体，但我们可以证明我们代码的突发擦除校正能力的理论下限优于 Matcha 代码。
Two dimensional magnetic recording systems are investigated extensively to achieve higher recording density. Since the recording density is very high, a small physical defect may cause many two dimensional errors. Hence many two dimensional signal processing of magnetic recording systems are also proposed and investigated. Matcha et al. have proposed a two dimensional LDPC code and investigated the error correcting performance of the code. In this paper we propose a code which is a variant of their code but we can show that the theoretical lower bound of the burst erasure correction capability of our code is better than that of Matcha's code.
