Abstract
A helical scan system (10) determines whether a medium is a non-native formatted medium and controls operating parameters (e.g., tape speed) so that a non-native formatted medium can be read without resort to embedded servo information in the non-native medium. The helical scan system reads the medium in a manner to obtain format-indicative information therefrom, and then determines whether the medium is non-native formatted. If the medium is non-native formatted, a controller determines operating parameters required by the system to read the non-native formatted medium and generates signals corresponding to the required operating parameters. The medium is preferably read in a slow speed mode in order to obtain format-indicative information therefrom, and block header information obtained from the medium is analyzed to determine whether the medium is non-native formatted.
