ABSTRACT:
In an apparatus for recording an electric signal on a magnetic record carrier (1) in tracks (T.sub.1, T.sub.2, . . . etc.) which are inclined relative to the longitudinal direction of the carrier the write head (4) comprises two head halves (K.sub.1, K.sub.2). The apparatus further comprises a signal source (3) for supplying a first and a second tracking signal (f.sub.1, f.sub.2) which are applied to the head halves (K.sub.1 and K.sub.2 respectively) of the write head for simultaneously recording the first and the second tracking signal, respectively in the first and the second track half of a track, in such a way that during the recording of consecutive tracks on a record carrier the first and the second tracking signals are recorded only in every n-th track (FIGS. 1 and 2a), n being an integer greater than 1 and preferably equal to 2. An apparatus for reproducing the electric signal recorded by means of said apparatus is also described. The crosstalk of the fist and the second tracking signal detected during reading is utilized for the purpose of tracking.
