Flying Head Read/Write Characteristics Using a Monolithically Integrated LD-PD at a Wavelength of 1.3 µm

Abstract

The LD-PD(1) is an oxidation-free, 1.3 µm wavelength InGaAsP laser diode monolithically integrated with a photodetector. A flying optical head(2) with an LD-PD on a slider is expected to be smaller, lighter, and less expensive than the conventional heads. In this paper, we analyze the read/write characteristics, the head/disk interface reliability, and the expected applications of the proposed head.
