ABSTRACT:
This invention discloses a flat data storage medium that includes a plurality of substantially parallel data arc-segments. The data arcs further include at least one full circle data track provided for obtaining a measurement of an average amplitude of data signals over the full circle data track for calibrating a pickup head implemented for reading data from the data arc-segments. This invention further discloses a data storage system for accessing data stored in a data storage medium. The data storage system includes dynamic head loading/unloading system that includes a handle for pushing a linkage connected to the handle for loading and unloading the data storage medium to an engaged and disengaged positions relative to a pickup head for accessing data disposed on the data storage medium. The dynamic head loading/unloading system further includes a locking mechanism for automatically locking the data storage medium inside the data storage system when the linkage is disposed at an engaged-position. The dynamic head loading/unloading system further includes a data-storage medium orientation-selection for cooperating and adapting the data storage medium inside the data storage system only when the data storage medium is inserted into the data storage system in a predefined orientation.
