摘要
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 υE 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 υA with respect to the transducing gap (37), the two acute angles υE and υA in the magnetic head (8, 9) being determined in such a way that ferrite material is uniformly worn off the two core limbs (34, 35) at essentially the same wear rate (K) when there is a relative movement between a record carrier (6) and the magnetic head (8, 9).
