Long-term digital preservation is an important issue in data storage area. For years, magnetic media based solutions, such as tape and hard disk drive (HDD) based archive systems, monopolize the data archiving market due to their high capacity and low cost. However, in the era of big data, rapidly increasing volume, velocity, and variety of data set bring numerous challenges to the archive systems in various aspects, such as capacity, cost, performance, reliability, power consumption, and so on… Expand
Ultra-high density optical data storage in common transparent plastics
TLDR
This work shows high-density data storage in commonly available plastics without any special material preparation using a pulsed laser to record data in micron-sized modified regions. Expand
Long-term data preservation on sapphire optical discs
The improved scheme of data recording process on an optical disc based on a substrate made of high-stable materials has been proposed. Information layer with depth of 115nm and width of 600nm hasExpand
A redistribution tool for long-term archive of astronomical observation data
TLDR
This study design and develop a tool referred to as AstroLayout to redistribute the observation data using spatial aggregation, which uses graph partitioning to generate an optimized data placement according to the original observation data statistics and the target storage system. Expand

Technology Roadmap Comparisons for TAPE, HDD, and NAND Flash: Implications for Data Storage Applications
TLDR
This paper describes the roadmap goals for tape based magnetic recording (TAPE) and uses these goals as counterpoints for the roadmap strategies for hard disk drive (HDD) and NAND flash and shows that presently volumetric efficiencies for TAPE, HDD, and Nand are similar. Expand
After Hard Drives—What Comes Next?
TLDR
To compete with hard drives on a cost per terabyte basis will be challenging for any solid state technology, because the ITRS lithography roadmap limits the density that most alternative technologies can achieve. Expand
An analysis of Facebook photo caching
TLDR
This paper instrumented every Facebook-controlled layer of the stack and sampled the resulting event stream to obtain traces covering over 77 million requests for more than 1 million unique photos to study traffic patterns, cache access patterns, geolocation of clients and servers, and to explore correlation between properties of the content and accesses.

Five-dimensional optical recording mediated by surface plasmons in gold nanorods
TLDR
This work shows true five-dimensional optical recording by exploiting the unique properties of the longitudinal surface plasmon resonance (SPR) of gold nanorods, which exhibits an excellent wavelength and polarization sensitivity, whereas the distinct energy threshold required for the photothermal recording mechanism provides the axial selectivity.
