Magnetic drum storage for digital information processing systems

Systems for Optical Storage and Processing of Information

Digital Drum Tutor

This thesis investigates issues surrounding the design and implementation of a digital drum tutor. People have been developing digital tutors in all fields of study in an attempt to replace or complement human instructors. This drum tutor aims to replace a human instructor in some cases, but mostly to guide a student’s practice sessions, which is where the most improvement occurs. While using t...

Holography for information storage and processing

We review recent progress made towards two types of holographic data storage systems. The first offers the potential for simultaneous search of an entire database by performing multiple optical correlations between stored data pages and a search argument [1,2]. This content–addressable retrieval produces one analog correlation score for each stored volume hologram. We review work we have perfor...

Digital Camera Image Formation: Processing and Storage

This chapter presents a high-level overview of image formation in a digital camera, highlighting aspects of potential interest in forensic applications. The discussion here focuses on image processing, especially processing steps related to concealing artifacts caused by camera hardware or that tend to create artifacts themselves. Image storage format issues are also discussed.

Detection and Decoding for Magnetic Storage Systems

The hard-disk storage industry is at a critical time as the current technologies are incapable of achieving densities beyond 500 Gb/in, which will be reached in a few years. Many radically new storage architectures have been proposed, which along with advanced signal processing algorithms are expected to achieve much higher densities. In this dissertation, various signal processing algorithms a...
