Spin-stand Microscopy of Hard Disk Data

This book provides an in-depth exposition of spin-stand microscopy of hard disk data. Spin-stand microscopy is the first magnetic rotating disk mounted on a spin-stand. This technique is one of the fastest scanning-based microscopy techniques. It is a non-invasive and has a nano-scale resolution. For these reasons, it provides unique recordings on hard disks. This book is self-contained, and has a wide range of applications, as well as experimental implementations, as well as its applications in hard disk diagnostics, imaging of overwritten patterns, computer forensics of hard disk files, and data-dependent magnetic thermal relaxations of recorded magnetization patterns. This book will be a valuable reference for the magnetic data, as well as the design of archival data storage systems.

Key features:

- a conceptual novelty of the wide range of applications
- detailed exposition of the principles of spin-stand magnetic microscopy
- comprehensive discussions of novel image reconstruction techniques
- demonstration of high resolution spin-stand images of hard disk data
- presentation of sector-by-sector ex-situ forensics of hard disk files
- extensive studies of data-dependent thermal relaxations of magnetization patterns recorded on hard disks
