ABSTRACT:
The present invention provides a magnetic recording and reproducing apparatus, a magnetic recording and reproducing method, and a thin film magnetic head that enable a good contact between elements and a recording medium with a reduced track pitch even if the number of head channels is increased, thereby realizing high recording density and high transfer rate.At least one multitrack write head having N (N is an integer of 2 or more) write elements arranged along a track width direction in an integral fashion and at least one multitrack read head having L (L is an integer equal to or more than N) read elements arranged along the track width direction in an integral fashion are formed on the rotary drum. The multitrack write head writes signals to a group of N tracks aligned parallel on the magnetic tape during one rotation of the rotary drum, and the multitrack read head reads the group of N signal tracks by the use of any one of the L read elements.
