  • Publication number: 20010038511
    Abstract: In a magnetic head (1) having a ring-like magnetic core (4) consisting of two core elements (9, 10) and having a terminating element (21) connected to the two core elements (9, 10) at the rear of the core elements (9, 10) by means of a connecting layer (23), the two core elements (9, 10) have a constant thickness and are without material recesses in their rear portion (8) and the connecting layer (23) between the two core elements (9,10) and the terminating element (21) consists of a layer having a high magnetic resistance, preferably of a non-magnetic material such as solder glass.

  • Patent number: 6246830
    Abstract: An apparatus for recording and reproducing video and audio signals in either analog or digital form. The heads are arranged to conform with existing analog standards, such as VHS, and yet are also able to record in digital form in adjacent non-overlapping tracks. In a preferred embodiment, one pair of heads is arranged with a small azimuth angle (+/−6 degrees), and another pair is arranged with a larger second azimuth angle (+/−30 degrees), conforming to the VHS standard, but the head width and location are modified compared to the standard such as to allow recording and reproducing both VHS as well as digital tapes.

  • Patent number: 5937137
    Abstract: An apparatus for recording and reproducing video and audio signals in either analog or digital form. The heads are arranged to conform with existing analog standards, such as VHS, and yet are also able to record in digital form in adjacent non-overlapping tracks. In a preferred embodiment, one pair of heads is arranged with a small azimuth angle (.+-.6 degrees), and another pair is arranged with a larger second azimuth angle (.+-.30 degrees), conforming to the VHS standard, but the head width and location are modified compared to the standard such as to allow recording and reproducing both VHS as well as digital tapes.

  • Patent number: 5933300
    Abstract: Recording and/or reproducing device (1) having at least one magnetic head (8, 9) provided for scanning a magnetic record carrier (6) and having a lead-in core limb (34) and a lead-out core limb (35) each consisting of a monocrystalline ferrite and constituting a transducing gap (37), in which the lead-in core limb (34) has a mechanical main direction (39) in a <100>-direction of its monocrystalline ferrite, which main direction encloses an acute angle .THETA..sub.E with respect to the transducing gap (37), and in which the lead-out core limb (35) has a mechanical main direction (41) in a <100>-direction of its monocrystalline ferrite, which main direction encloses a second acute angle .THETA..sub.A with respect to the transducing gap (37), the two acute angles .THETA..sub.E and .THETA..sub.

  • Patent number: 5210668
    Abstract: Magnetic head comprising a magnetic core having two core limbs (1,3) formed from a ferrite, which core limbs constitute two core faces located opposite each other, at least one of said core faces having a cladding of a soft-magnetic material having a higher saturation magnetisation than the ferrite, and a non-magnetic transducing gap (11) present between the core faces and having at least one layer of a first metallic material (21) and bonded layers (23) of a second metallic material. The cladding comprises a first cladding layer (15) of an alloy based on Ni-Fe on which a second cladding layer (17) of an amorphous alloy based on Co-Ti and/or Zr and/or Hf-Nb and/or Ta is provided, while the first metallic material, chosen from the group of Mo, Ti, Cr and NiCr, is directly provided on the amorphous alloy of the cladding. (FIG. 2).

  • Patent number: 4905111
    Abstract: A damping material (19) is provided on one of the two side faces (7, 8), of a magnetic head having two plate shaped ferrite core limbs (3, 4). The material consists of a synthetic resin filled with less than 30% by volume of filler having a density of more than 10.times.10.sup.3 kg/m.sup.3. The filler is at least 74% by weight of the damping material and the density of the damping material is larger than 4.times.10.sup.3 kg/m.sup.3 and its modulus of elasticity ranges between 10.sup.7 and 10.sup.9 Pa.
