The importance of magnetostatics in video recording: a theoretical analysis

Magnetic recording involving the storage of analog video signals is investigated by computer simulation of the writing and reading process. In this theoretical analysis, the writing and playback of full video signals and of a high-frequency sine-wave on video tape is modeled for the video home system (VHS) and the super-VHS in particular. The influence and importance of various media and system data are determined for the storage performance of the chrominance and luminance part of the video signal. The calculated relationships between tape data and output performance elucidate the importance of the various tape properties and enable the tape producer to develop and optimize videotapes.<
