Abstract

En mekanisme for nøyaktig følging av senteret til et spor innbefatter en talespole (22) eller en talespole (22) og en skrittmotor (32) i kombinasjon. Talespole-skrittmotor-kombinasjonen virker for variabelt å posisjonere et opptakshode (12) på tvers med hensyn til bredden av magnetbåndet. Mekanismen tillater posisjonering av hodet med meget små toleranser på grunn av talespolens evne til fint å posisjonere hodet meget nøyaktig på sentrum av et spor.
