This article will describe a series of experiments we conducted for the purpose of pursuing the resolution limit of the PTM process. Disc samples with different track pitches and different linear densities were prepared through the PTM process. The signal properties of these discs were analyzed with the assistance of a near field readout system. The jitter value was 5.6% at the linear density of 70nm/bit and 0.16μm track pitch, which corresponded to 80GB per 12cm diameter disc. Even at a recording density corresponding to a capacity of 100GB we observed jitter values less than 10%.
