ABSTRACT:
The reliability of data transfer between stages of photographic filmstrip use and processing is enhanced by magnetically recording a limited data set repetitively along a wide track in a frame of the filmstrip. Plural laterally offset magnetic read heads monitor the data in the magnetic track and provide output data signals on parallel independently operating channels. The data content of the output data signals is examined to determine whether the data of an individual data signal contains corruption error. The combined linear and parallel redundancy of the system tends to ensure successful data transfer despite a less than perfect head-to-film interface and other data corrupting influences.
