Abstract

Περιγράφεται ένας φορέας εγγραφής (1) που έχει ένα σερβοδίαυλο (4) που δείχνει ένα ίχνος πληροφοριών (9) που προορίζεται για την εγγραφή μπλοκ πληροφοριών. Ο σερβοδίαυλος (4) έχει μια περιοδική μεταβολή μιας φυσικής παραμέτρου, σε μια προκαθορισμένη συχνότητα, που συνήθως ονομάζεται ταλάντευση, ο σερβοδίαυλος έχει διαμορφωμένα μέρη για πληροφορίες θέσης κωδικοποίησης σύμφωνα με έναν προκαθορισμένο τύπο διαμόρφωσης. Ο φορέας εγγραφής περιλαμβάνει ένα χώρο διαχείρισης στον οποίο ο σερβοδίαυλος περιλαμβάνει μόνιμα δεδομένα. Τα μόνιμα δεδομένα κωδικοποιούνται χρησιμοποιώντας έναν διαφορετικό τύπο διαμόρφωσης, αλλά χρησιμοποιώντας τις παραλλαγές της ίδιας φυσικής παραμέτρου. Η άμεση ψηφιακή διαμόρφωση (41), προτείνεται για τον διαφορετικό τύπο διαμόρφωσης. Περαιτέρω περιγράφεται μια συσκευή για την ανάγνωση ή/και την εγγραφή του φορέα εγγραφής.
