Abstract
Abstract A magnetic head includes a core securely mounted on core support or coil connector. The coil connector is provided at one end with a hole in which the core is fitted for preventing the separation of the connector. An end of an insulating member is inserted between the coil and support for preventing short-circuiting of the coil by contact with the support.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
114 words
A magnetic head for at least one of recording information on and reading information from a recording medium, the information being processed by information processing means, said magnetic head comprising: support means formed with at least one aperture; connecting means, having electrical contact means thereon, supported on said support means and formed with at least one aperture; and at least one magnetic head element, connected by said electrical contact means on said connecting means to the information processing means, also supported on said support means and received in an aperture therein and in an aperture in said connecting means, portions of said magnetic head element holding therebetween said support means and said connecting means.
Claim 2
Dependent Claim
114 words
A magnetic head for at least one of recording information on and reading information from a recording medium, the information being processed by information processing means, said magnetic head comprising: support means formed with at least one aperture; connecting means, having electrical contact means thereon, supported on said support means and formed with at least one aperture; and at least one magnetic head element, connected by said electrical contact means on said connecting means to the information processing means, also supported on said support means and received in an aperture therein and in an aperture in said connecting means, portions of said magnetic head element holding therebetween said support means and said connecting means.
Claim 3
Dependent Claim
63 words
A magnetic head according to the claim 1, wherein said magnetic head elements comprise at least one magnetic core and a coil wound thereon, and said support means and said connecting means are held between a part of said magnetic core and said coil, which thereby comprise said portions of said magnetic head elements, at a location in the proximity of said apertures.
Claim 4
Dependent Claim
26 words
A magnetic head according to the claim 2, further comprising terminals for said coil, said terminals being connected to said connecting means at a portion thereof.
Claim 5
Dependent Claim
31 words
A magnetic head according to the claim 1, wherein said support means comprises an elastic member for elastically supporting said magnetic head elements, and said connecting means comprises a flexible member.
Claim 6
Dependent Claim
97 words
A magnetic head, comprising: a first member including a conductor and provided with at least one aperture; a second member including an electrical insulator provided with at least one aperture and at least one conductor formed on said insulator; and at least one magnetic head element including at least one magnetic core comprising a material of high magnetic permeability and received in said apertures in each of said first member and said second member; said magnetic head element further comprising a coil wound on said core at a position adjacent said electrical insulator of said second member.
Claim 7
Dependent Claim
97 words
A magnetic head, comprising: a first member including a conductor and provided with at least one aperture; a second member including an electrical insulator provided with at least one aperture and at least one conductor formed on said insulator; and at least one magnetic head element including at least one magnetic core comprising a material of high magnetic permeability and received in said apertures in each of said first member and said second member; said magnetic head element further comprising a coil wound on said core at a position adjacent said electrical insulator of said second member.
Claim 8
Dependent Claim
21 words
A magnetic head according to the claim 5, wherein said coil includes terminals connected to said conductor of said second member.
