Tone-Controllable Codes for Holographic Data Storage System

초록

The first merit of the holographic data storage (HDS) system is its high storage capacity. In practice, it is well known that the total capacity for the storage medium depends on the appropriate ratio of ON and OFF pixels within data pages. Therefore, we propose a modulation code that can control the ratio of ON and OFF pixels. We refer to this code as "tone-controllable code". In this paper, we introduce the encoding/decoding rules and simulate the bit error rate (BER) performance of the tone-controllable codes having various ratios of ON and OFF pixels.
