In a recorder having two inline heads, such as a record head followed by a reproduce head, it is necessary to insure adequate tape wrap angle at the transducing element of each head. Because the tape is spanned between the two inline heads, the tape leaves the apex of one head at a zero wrap angle and arrives at the apex of the second head with a zero wrap angle. The invention provides outriggers on each head assembly which guide the tape, and teaches placing each transducing element off the apex of its head assembly to maintain adequate wrap angles at the transducing elements of each inline head. The outriggers are provided with slots which skive entrapped air to prevent tape "flying" with attendant loss of contact with the transducing elements. The contours of the outriggers and the lands on which the transducing elements of each head assembly are located form constant area profiles to provide constant wear characteristics for the head assemblies.
