Magnetic head adjustment assembly

Claim 2

In a magnetic head mounting system including a magnetic transducer, a suspension member for supporting the magnetic transducer and a movable carriage unit along a suspension axis, the improvement of means for mounting the suspension member to the carriage unit, said mounting means comprising: A. a mount affixed to the suspension member for mounting the suspension member and head in the carriage, said mount including a flat surface portion and an end portion; B. adjustable stop means for engaging said end portion to thereby position said mount in the carriage along the suspension axis; and C. a locking unit with a surface thereon for engaging said flat surface to thereby prevent rotation of said mount about the suspension axis in the carriage during axial displacement.

Claim 3

A magnetic head mounting system as recited in claim 1 wherein said locking means comprises: A. a locking screw with a conical end portion, and B. a flat on said mount engaging said conical end portion.

Claim 4

In a magnetic disk storage unit with a rotatable record, a magnetic transducer disposed in operative association with opposite sides of the record, a suspension member for each transducer lying generally along a suspension axis parallel to a record radius, and a carriage for moving the transducers along their respective suspension axes, the carriage having a pair of spaced, vertically aligned, horizontal bores, the improvement of means for connecting each transducer to the carriage unit for facilitating alignment of individual transducers with their respective record surfaces, said connecting means comprising: A. an adjustable stop means mounted in the carriage for each bore, B. a mount in each bore with one end affixed to a respective one of the suspension members and extending generally along a respective one of the suspension axes, each of said mounts having a supporting portion partially cylindrical outer surface for engaging the carriage in the bore, an end of said supporting portion defining a wedging surface in alignment with a respective one of said adjustable stop means and an intermediate portion spaced from said end, and lugs offset from said end and intermediate portions, each lug having a partially cylindrical surface forming a bearing surface which interfits on the bore opposite one of said mounts being oppositely oriented about its suspension axis with respect to the other, whereby said adjustable stop means for each mounting member is accessible from the top of said carriage, said adjustable stop means for the lower mount passing said upper mount at positions offset from said lugs.

Claim 5

In a magnetic disk storage unit with a rotatable record, a magnetic transducer disposed in operative association with opposite sides of the record, a suspension member for each transducer lying generally along a suspension axis parallel to a record radius, and a carriage for moving the transducers along their respective suspension axes, the carriage having a pair of spaced, vertically aligned, horizontal bores, the improvement of means for connecting each transducer to the carriage unit for facilitating alignment of individual transducers with their respective record surfaces, said connecting means comprising: A. an adjustable stop means mounted in the carriage for each bore, B. a mount in each bore with one end affixed to a respective one of the suspension members and extending generally along a respective one of the suspension axes, each of said mounts having a supporting portion partially cylindrical outer surface for engaging the carriage in the bore, an end of said supporting portion defining a wedging surface in alignment with a respective one of said adjustable stop means and an intermediate portion spaced from said end, and lugs offset from said end and intermediate portions, each lug having a partially cylindrical surface forming a bearing surface which interfits on the bore opposite one of said mounts being oppositely oriented about its suspension axis with respect to the other, whereby said adjustable stop means for each mounting member is accessible from the top of said carriage, said adjustable stop means for the lower mount passing said upper mount at positions offset from said lugs.

Claim 6

A magnetic disk assembly as recited in claim 3 additionally comprising: A. flats formed at said intermediate portions; and B. locking units for each mount vertically aligned for engaging one flat to lock said mounts in place and, during alignment, to nunize head rotation.

Claim 7

A magnetic disk storage unit as recited in claim 4 wherein: A. each locking unit comprises a screw mounting along an axis intersecting the bore for its respective mount, each screw having a conical end portion, and B. said flat on each mount engaging said conical surface along a substantial portion of the length thereof.
