Abstract

With the rapid deployment of 5G communication facilities, cloud computing, artificial intelligence, etc., the amount of data is growing explosively. According to International Data Corporation(IDC), the total amount of data in 2018 is 32ZB, and it is expected to reach 175ZB by 2025, of which 10%~15% is cold data. Cold data features as infrequent access and rare modification, but great longevity. Taking the cost of storing cold data into consideration, optical storage, especially, the write once read many recording media(WORM) become one of the most appropriate candidates for this scenario. To accelerate developing drive techs for new generation WORM, we choose the heterogeneous platform, upon which FPGA and DSP are resided, to develop servo and RF channels, in order to provide agility and flexibility in both modeling and tuning.
