摘要： This invention discloses a data storage system for accessing data stored in a data storage medium. The data storage system includes a motor-head assembly controlled to activate a vertical movement for loading and unloading at least a pickup head supported thereon to access the data medium in the data storage medium. For a specific data-storage system configuration, the motor-head assembly further includes a rotating motor for rotating the pickup head when the pickup head is loaded onto the data storage medium. In another system configuration, the data storage system implemented with a motor to move the data storage medium in at least one linear direction or for rotating the data storage medium. The motor-head assembly further includes a vertical-position locking hook for automatically pulling away the pickup head from the data storage media when the motor-head assembly is unloaded from the data storage medium. The vertical-position locking linkage further automatically unlock the pickup head in an unconstrained compliance state next to the data storage medium when the motor-head assembly is loaded to the data storage medium.

The data access system further includes at least one stepping motor for discretely moving the flat medium substantially along at least one lateral direction perpendicular to a rotational axis of the pickup head. The data access system further includes a closed loop control mechanism for controlling the stepping motor for allowing the pickup head to read data from a servo segment on the flat medium. The controller further includes an open loop control mechanism for rotating the pickup head for reading data from and writing data to a data segment disposed right next to the servo segment on the flat medium.
