Abstract
A device for the magnetic recording and/or playing back of signals on a flexible recording medium (4) includes a magnetic transducing head (2) and transport and guide means (8, 8') for bringing successive parts of a flexible recording medium (4) in physical contact with a surface (1, 10) of the head. The head surface is curved and comprises a non-magnetic transducing gap (3) which intersects the direction of movement of the recording medium to obtain an optimum contact between recording medium (4) and head (2) at the area of the transducing gap (3). The radius of curvature of the contact face (10) of the head (2) with the recording medium (4) has a maximum value at the area of the transducing gap (3) and decreases from the transducing gap (3) to both the part of the head where the recording medium moves towards the transducing gap and to the part of the head where the recording medium moves away from the transducing gap (3).
