Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
214 words
A METHOD OF PRODUCING A TRANSDUCER HEAD FOR PROVIDING A TRANSDUCING ACTION BETWEEN THE HEAD AND A MOVABLE MEDIUM, INCLUDING THE STEPS OF: PROVIDING FIRST AND SECOND MAGNETIC MEMBERS TO DEFINE A GAP BETWEEN THE MAGNETIC MEMBERS UPON A DISPOSITION OF THE MAGNETIC MEMBERS IN CONTIGUOUS RELATIONSHIP TO EACH OTHER TO OBTAIN A DISPOSITION OF THE GAP IN CONTIGUOUS RELATIONSHIP TO THE MOVABLE MEDIUM, DEPOSITING A LAYER OF A FIRST MATERIAL ON EACH OF THE FIRST AND SECOND MAGNETIC MEMBERS WHERE THE FIRST LAYER HAS A FIRST PARTICULAR MELTING TEMPERATURE, DEPOSITING A LAYER OF A SECOND MATERIAL ON THE FIRST MATERIAL ON EACH OF THE FIRST AND SECOND MAGNETIC MEMBERS WHERE THE SECOND MATERIAL HAS A SECOND PARTICULAR MELTING TEMPERATURE LOWER THAN THE FIRST PARTICULAR MELTING TEMPERATURE, DISPOSING THE FIRST AND SECOND MEMBERS IN CONTIGUOUS RELATIONSHIP TO EACH OTHER, AND HEATING THE FIRST AND SECOND MAGNETIC MEMBERS AND THE FIRST AND SECOND LAYERS TO A PARTICULAR TEMPERATURE GREATER THAN THE SECOND PARTICULAR MELTING TEMPERATURE BUT LESS THAN THE FIRST PARTICULAR MELTING TEMPERATURE WITH THE MAGNETIC MEMBERS IN CONTIGUOUS RELATIONSHIP TO ONE ANOTHER TO OBTAIN AN ALLOY OF THE FIRST AND SECOND MATERIALS AND A BONDING OF THE FIRST AND SECOND MATERIALS FOR THE PRODUCTION OF A CONTINUOUS GAP BETWEEN THE FIRST AND SECOND MATERIALS.
Claim 2
Independent Claim

A METHOD OF PRODUCING A TRANSDUCER HEAD FOR PROVIDING A TRANSDUCING ACTION BETWEEN THE HEAD AND A MOVABLE MEDIUM, INCLUDING THE STEPS OF: PROVIDING FIRST AND SECOND MAGNETIC MEMBERS TO DEFINE A GAP BETWEEN THE MAGNETIC MEMBERS UPON A DISPOSITION OF THE MAGNETIC MEMBERS IN CONTIGUOUS RELATIONSHIP TO EACH OTHER TO OBTAIN A DISPOSITION OF THE GAP IN CONTIGUOUS RELATIONSHIP TO THE MOVABLE MEDIUM, DEPOSITING A LAYER OF A FIRST MATERIAL ON EACH OF THE FIRST AND SECOND MAGNETIC MEMBERS WHERE THE FIRST LAYER HAS A FIRST PARTICULAR MELTING TEMPERATURE, DEPOSITING A LAYER OF A SECOND MATERIAL ON THE FIRST MATERIAL ON EACH OF THE FIRST AND SECOND MAGNETIC MEMBERS WHERE THE SECOND MATERIAL HAS A SECOND PARTICULAR MELTING TEMPERATURE LOWER THAN THE FIRST PARTICULAR MELTING TEMPERATURE, DISPOSING THE FIRST AND SECOND MEMBERS IN CONTIGUOUS RELATIONSHIP TO EACH OTHER, AND HEATING THE FIRST AND SECOND MAGNETIC MEMBERS AND THE FIRST AND SECOND LAYERS TO A PARTICULAR TEMPERATURE GREATER THAN THE SECOND PARTICULAR MELTING TEMPERATURE BUT LESS THAN THE FIRST PARTICULAR MELTING TEMPERATURE WITH THE MAGNETIC MEMBERS IN CONTIGUOUS RELATIONSHIP TO ONE ANOTHER TO OBTAIN AN ALLOY OF THE FIRST AND SECOND MATERIALS AND A BONDING OF THE FIRST AND SECOND MATERIALS FOR THE PRODUCTION OF A CONTINUOUS GAP BETWEEN THE FIRST AND SECOND MATERIALS.
Claim 3
Dependent Claim
72 words
THE METHOD SET FORTH IN CLAIM 1 WHEREIN THE FIRST AND SECOND MAGNETIC MEMBERS ARE DISPOSED IN A CASING AND ARE POTTED IN A MATERIAL HAVING A REACTING TEMPERATURE APPROXIMATELY EQUAL TO THE PARTICULAR TEMPERATURE TO WHICH THE FIRST AND SECOND MAGNETIC MEMBERS ARE HEATED AFTER THE LAYERS OF THE FIRST AND SECOND MATERIALS HAVE BEEN DEPOSITED ON THE MAGNETIC MEMBERS AND WHERE THE POTTING MATERIAL BECOMES HARDENED AT THE REACTING TEMPERATURE.
