In a wideband, transverse scan magnetic tape recording system, such as used for video signals, a standard transport is modified for recording high resolution and magnetically durable master tapes to be used in making multiple copies thereof by a contact duplicating process in which a blank tape is brought into face-to-face contact with the master tape. In particular, the transport for recording the master tape is arranged to record the transverse magnetic tracks in a pattern having a reflected or mirror image relationship with the tracking format carried by tapes adapted for playback on a standard transverse scan transport. The contact duplicate of the master thus receives the proper magnetic image for playback on standard machines. The modifications which are made to the standard recording mechanism are such that a single transport unit may be employed for recording of the master tape, playback of the contact duplicate tapes made therefrom, or recording and playback of other standard tapes, by interchanging a few component parts and making certain minor adjustments to the standard unit depending on the desired use.
