Abstract:
1. An information recording apparatus capable of carrying out tracking servo control by reading with a servo head servo stripes recorded on magnetic tape with an inclination in a longitudinal direction of the magnetic tape, the information recording apparatus comprising: two servo head groups each provided on both sides of a data head group, each of the servo head groups being composed of N servo heads (N≧2), the N servo heads aligned in a width direction of the magnetic tape; a delay means for delaying N servo signals reproduced by the N servo heads for a predetermined time; an adding means for adding up N servo signals outputted from the delay means; a signal processing means for generating tracking information from a servo signal outputted from the adding means; and a delay time control means for controlling a delay time of the delay means, wherein the delay time control means controls the delay time of the delay means so that peak timings of N servo signals with a time lag reproduced by the N servo heads coincide with each other.
