Pulse noise in thin film disk recording systems

The effect of media noise on pulse amplitude and pulse shape variation has been investigated at a thin film disk drive. In a new approach total amplitude noise is divided into a reproducible (deterministic) part and a random part. At higher pulse interference position jitter is identified as source...

Description
Summary:The effect of media noise on pulse amplitude and pulse shape variation has been investigated at a thin film disk drive. In a new approach total amplitude noise is divided into a reproducible (deterministic) part and a random part. At higher pulse interference position jitter is identified as source of additional random amplitude noise. From pulse shape analysis it is concluded that flying height and transition length are the reasons for the observed amplitude variations.
