Abstract

Båndspiller med et magnethode i form av et kombinasjonshode (13) og innrettet for innspilling/avspilling av spor som følger en serpentinlignende bane. Båndspilleren har et magnetisk opptaksmedium i form av et bånd (11) og er innrettet for å spille inn både datasignaler og servosignaler. Servo-signalene innspilles/avspilles ved hjelp av servohoder (Sl,Sl'-S4,S4') som er anordnet i kombinasjonshodet (13) og benyttes for posisjonering av dette i forhold til båndet (11). Innspillingen av datasignaler skjer ved hjelp av datainnspillingshoder (W11-W14), og avspillingen skjer ved hjelp av data-avspillingshoder (R11-R14). Samtidig med avspillingen foregår en posi-sjonsregulering av kombinasjonshodet (13), og posisjonsreguleringen bestem-mes av minst ett av de servosignaler som er innspilt på båndet (11) og som blir avspilt med servoavspillings-hodene.Tape recorder with a magnetic head in the form of a combination head (13) and arranged for recording / playback of tracks that follow a serpentine-like path. The tape recorder has a magnetic recording medium in the form of a tape (11) and is arranged to record both data signals and servo signals. The servo signals are recorded / played back by means of servo heads (S1, S1'-S4, S4 ') which are arranged in the combination head (13) and are used for positioning this in relation to the band (11). Data signals are recorded using data recording heads (W11-W14), and playback is performed using data playback heads (R11-R14). Simultaneously with the playback, a position control of the combination head (13) takes place, and the position control is determined by at least one of the servo signals recorded on the tape (11) and which is played back with the servo play heads.
