2.5.2 Read ID String

Die über den „Read ID String" ausgelesenen Daten beinhalten
AS-Interface spezifi sche Informationen über den Schreib-/
Lesekopf.
Hier sind Informationen gespeichert, die Auskunft über
das Verhalten des Schreib-/Lesekopf (ID15/SLK)s am
AS-Interface geben. Die Datenstruktur dieses Strings ist
weitgehend in der AS-Interface-Spezifi kation beschrieben. Um
einen Überblick über die dort gespeicherten Daten sowie eine
Hilfe zur Interpretation zu geben, ist untenstehende Tabelle zu
betrachten.

2.5.2 Read ID string
The data read out via the „read ID string" contains AS-
interface specifi c information on the read/write head (ID15/
SLK).
Information is stored here that provides details on how the
read/write head (ID15/SLK) acts in the AS-interface. The
data structure of this string is extensively described in the
AS-interface specifi cations. The following table provides an
overview of the data stored there and can also be used for
interpretation.
