Design and Fabrication of A High Density Metal Microelectrode Array for Neural Recording

We report a new fabrication technique for realizing a high-density penetrating metal microelectrode array intended for acute multipleunit neural recordings. The microelectrode array consists of multiple metal (Permalloy, Ni80Fe20) shanks projecting from a silicon supporting bulk. Neuron recording sites are located at the tip of each shank. The average distance between recording sites is 50 μm. ...

Towards ultra high density multi-layer disk recording by two- photon absorption

The influence of the numerical aperture on a 3-D multi-layer optical data storage system is analyzed by simulation and validated experimentally. By increasing NA it becomes feasible to store more than a terabyte of data in a two-photon recorded 5 1⁄4” disk media.

High Density Pcm Magnetic Tape Recording

The Bell & Howell Enhanced-NRZ recording reproducing technique for bit packing densities up to 40,000 per track inch is described in this paper. Utilization of the pulse code modulation format of Enhanced-NRZ achieves this high density with a bit error rate of one in ten million. Bell & Howell’s standard VR-3700B instrumentation tape recorder and wideband instrumentation recording tape are used...

Reduced-Complexity Turbo Equalization for High-Density Magnetic Recording Systems

This paper considers a decision-feedback-equalizer (DFE)-based soft decision detector as an alternative for the Bahl–Cocke–Jelinek–Raviv (BCJR) front-end for a coded magnetic recording channel. In previous work, a bidirectional-arbitrated DFE (BAD) was shown to perform in between a BCJR detector and a minimum mean-square error DFE. We propose a soft-output BAD (S-BAD) which takes advantage of t...
