Method and apparatus for magnetic communication via a photographic filmstrip using trappable data sentinels |
摘要 |
Overhead and data loss are reduced when transferring data via magnetic recording in a magnetic layer of an elongate photographic filmstrip, by providing a trappable data sentinel at the beginning of a data field. The data sentinel comprises a pair of reserved characters which establish a data character boundary for data in the field and also identify the nature of this data. The data sentinel is trapped by an identity comparator and also read by a host computer or processor. Data fields employing the data sentinel format can be embedded within a start sentinel/end sentinel track architecture.
