Latest Patents

One of his latest patents is a data card with a full circular track for alignment and amplitude calibration. 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 also discloses a data storage system for accessing data stored in a data storage medium. The data storage system includes a dynamic head loading/unloading system that features a handle for pushing a linkage connected to the handle for loading and unloading the data storage medium to engaged and disengaged positions relative to a pickup head for accessing data disposed on the data storage medium. Additionally, the dynamic head loading/unloading system 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. It also features 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.

Another significant patent by Shand-Ling Mao involves the positioning of a recording head for a data storage device. This invention is 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 is 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 also 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
