A general strategy for fabricating thick, optically flat photopolymer recording media with high dynamic range (M/#) that exhibit low levels of recording-induced Bragg detuning for holographic data storage is presented. In particular, media with M/# values as high as 42 in 1-mm-thick formats are obtained. We believe that these results are the first demonstration of a holographic storage medium w...

Recording Characteristics of Co-Cr Perpendicular Magnetic Recording Media Prepared by ECR Sputtering
Recording experiments and decoding algorithms are presented for evaluating the bit-error-rate of state-of-the-art magnetic bitpatterned media. The recording experiments are performed with a static tester and conventional hard-disk-drive heads. As the reader dimensions are larger than the bit dimensions in both the down-track and the cross-track directions, a two-dimensional bit decoding algorit...
In this paper, we review many of the technical issues that must be addressed in developing high-quality optical disk recording media. The geometric design of tracking grooves and embossed data on the disk substrate must be optimized to the characteristics of the optical drive to support robust data seeking, track following, and data addressing. To ensure adequate recording performance and drive...
In magnetic recording media, the remanent magnetization loop, Mr(H)has some parameters, which explain the prperties of the medium in view of the storage density and signal-to-noise ratio. It is necessary to find the mechanism of Mr variations from the statistical characteristics of the system. We have prepared samples of single-domain ascicolar iron particles with 0.3 length, and the oriented...
