Abstract :
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.
