摘要

我们提出了一种新的记录方法，称为槽基记录(GBR)。在GBR中，码间干扰(ISI)的影响通过QAM等数字调制来消除。由此产生的模拟波形的数字调制是浮雕记录的凹槽壁的摆动。我们的初步实验表明，我们可以实现比DVD高1.5倍的面积密度。

GBR (groove baseband recording) for an optical disc ROM

We have proposed a new recording method called groove base recording (GBR). In GBR the effect of intersymbol interference (ISI) is removed by a digital modulation such as QAM. The resultant analog waveform of the digital modulation is emboss recorded by a wobble of groove walls. Our preliminarily experiment suggested that we can achieve 1.5 times higher area density than that of DVD.
