Filed: 1998-01-14
Abstract: PROBLEM TO BE SOLVED: To decide the normality of a data order by comparing quantity of data that is transmitted by a communication processor with quantity of data of which communication processing is completed. SOLUTION: When value DP that is written from a data processor 11' is below the sum of data number X2 which is completed transmission processing and data number (n) which can be transmitted through bidirectional memory 31 at one time, it is normal. If it exceeds the sum, data number that is transmitted is too large than data number that is performed transmission processing, it is decided that abnormality occurs, and '1' is written to the bidirectional memory EF and the processing is finished. When there is no abnormality, it is decided whether or not data number DP that is next transmitted is below the data number X2 that is completed transmission processing. When the DP is below the X2, it is decided that abnormality occurs and '1' is written to the memory EF.  And when there is no abnormality, next, an index register Y2 which stores an offset of the memory EF is made '0' and this makes it possible to access from a leading address DM+0 of the memory 31.

Abstract: PURPOSE:To produce a recording medium which excels in the corrosion resistance of a magnetic layer by forming a recording magnetic layer on a substrate under vacuum, a thin film of a metal or an oxide contacting to the recording magnetic layer without breaking the vacuum state and then a protecting film in another vacuum tank. CONSTITUTION:An amorphous recording magnetic layer is formed on a substrate by sputtering under vacuum. Then a thin film of a metal or an oxide is formed with about 200Angstrom  thickness on said recording magnetic layer in the same vacuum tank by sputtering without breaking the vacuum state. In this case, the metal uses Ti, Al, Si, Cr, etc,; while the oxide uses TiO2, Al2O3, SiO2, CrO3, etc. Then a protecting film of 2,000-3,000Angstrom  thickness is formed on the thin film in another vacuum tank. This protecting film can use a material same as or different from the thin film. Thus said thin layer is previously formed on the recording magnetic layer in the same vacuum tank without breaking the vacuum state of the tank where the recording magnetic layer is formed when the protecting film is formed.
