Abstract
An alignment tape for magnetic recording and playback devices contains recorded tracks useful for aligning the tape path on a rotating drum. The recorded tracks are spaced apart a sufficient distance to avoid interference from adjacent recorded tracks when the playback head is off-track. The alignment tracks are spaced apart a distance equal to the distance normally occupied by three tracks. This ensures that interference from an adjacent track when the head is off-track is minimized or eliminated. An apparatus is disclosed for controlling the recording of the alignment tape.
