Title:
MAGNETIC RECORDING DEVICE FOR CAMERA
Document Type and Number:
Japanese Patent JP3420088
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make effectively storable photographing information recorded in a magnetic track even in the case of an information storing means whose memory capacity is small by storing only data having possibility that the data are changed every time photographing operation is performed out of information to be recorded by a magnetic recording means.
SOLUTION: The data stored in an E2PROM 103, which can be electrically erased, are numerical data. The data for discriminating the numerical data are used in common to any photographing data, and it is waste of a memory to store the data in the E2PROM 103 every time photographing is performed. Then, it is necessary to store the numerical data having the possibility that it is changed every time photographing is performed in the E2PROM 103 as a means for efficiently using the memory. Therefore, the data for discriminating is stored in the program memory of a μCOM 100 and only the numerical data is recorded in the E2PROM 103, so that the capacity of the E2RPOM 103 is increased.
