Latest Patents
Kaji's latest patents include a method of checking magnetic heads and an innovative film carrier. The method of checking magnetic heads involves a systematic approach to ensure that both the reading head and recording head are functioning correctly. This is achieved by applying direct current voltage to the recording head when a negative film begins to be withdrawn. The system detects the leading end of the negative film and conveys it a fixed amount to record and read data for checking. If discrepancies arise between the read data and the data for checking, it indicates an abnormality in the heads, prompting error processing.
The film carrier patent describes a device that accurately guides a film while allowing a magnetic or optical head to follow its edge. This design ensures that the positional relationship between the recording portion and the head remains fixed, even when navigating concave portions of the film's edge. This innovation allows for correct recording or reading of information without damaging the film.
