Abstract
In a cleaning mechanism for a magnetic head which mechanically cleans a recording/reproducing face of a magnetic head by using a cleaning brush, a basal portion of which is supported by a device fixing portion, a resin block is fixed to an end portion of an L-shaped brush stem of the cleaning brush, the brush stem being made of a metal plate, and a number of brush pieces which are to come into contact with the recording/reproducing face are formed integrally with the resin block.
Claims11
A cleaning mechanism for a magnetic head having a recording/reproducing face, said cleaning mechanism for contacting said recording/reproducing face and comprising:
- a basal portion supported by a device fixing portion connected to said magnetic head;
- an L-shaped brush stem connected swingably to said basal portion, said L-shaped brush stem comprising a metal plate and having an end portion;
- a resin block covering and connected to said end portion of said L-shaped brush stem;
- and
- at least one brush piece molded integrally with said resin block, such that said resin block and said resin brush comprise a single monolithic structure, wherein said brush piece comprises a strip of flexible material positioned along a length of said resin block.
A magnetic head assembly comprising:
- a magnetic head having a recording surface;
- a resin brush connected swingably to said magnetic head for cleaning said recording surface, wherein said brush includes a stem and a resin block connected to said stem, said block including at least one resin brush piece, wherein said resin block and said at least one resin brush piece are integrally formed and comprise a single monolithic structure,
- wherein said brush piece comprises a strip of flexible material positioned along a length of said block.
A cleaning mechanism for a magnetic head assembly including a brush having a stem, said brush being made by a process comprising steps of:
- placing said stem in a mold;
- and
- injecting a flexible material in said mold to integrally form a block and at least one brush piece on an end of said stem,
- wherein said mold includes an upper mold and a lower mold forming a block cavity having a shape of said block said upper mold including at least one brush void having a shape of said at least one brush piece,
- wherein said block cavity and said brush void comprise a continuous opening.
