Tracking control apparatus which uses pilot signals to control a capstan |
摘要 |
An information reproducing apparatus for reproducing information recorded on slant information tracks includes magnetic heads mounted on a rotary cylinder. The magnetic heads scan a magnetic tape which has slant information tracks on which tracking pilot signals are formed. A tracking error detector detects the tracking error signal of the magnetic head scanning using the tracking pilot signal recorded on the slant information tracks. The tracking error detector then generates a tracking error signal indicating the amount of the track bending. A control signal generator generates a control signal in response to the tracking error signal for controlling the scanning position of the magnetic head. A tracking controller controls the slant track scanning position of the magnetic head.
