Patent ID: 8351147

Claim:
A data storage apparatus comprising: a mounting structure; a data storage unit comprising a data storage platter mechanically attached to a first motor attached to said mounting structure, wherein said data storage platter comprises a data storage portion and a spindle portion, wherein said spindle portion is mechanically attached to a spindle of said first motor, wherein said first motor is configured to rotate said data storage platter, wherein said data storage platter comprises a circular shape, wherein said data storage portion is located within a top surface of said data storage platter, wherein said data storage portion comprises data sections, and wherein said spindle portion is located within a center of a rotation portion of said data storage platter; an actuator motor mechanically attached to said mounting structure; a single actuator arm mechanically attached to said actuator motor, wherein said single actuator arm is configured to move axially along an arc and across said top surface of said data storage platter, wherein said single actuator arm comprises a first read/write data head and a second read/write data head, wherein said first read/write data head is located on said single actuator arm such that said first read/write data head has access to a first section and a second section of said data sections, wherein said second section differs from said first section, and wherein said second read/write data head is located on said single actuator arm such that said second read/write data head has access to only said second section; and a control circuit controlling communications to said first read/write data head and said second read/write data head, wherein the control circuit is configured to selectively enable or disable communications to said first read/write data head and said second read/write data head in response to detecting which of said first read/write data head or said second read/write data head is currently configured to read data from said data storage platter or write data to said data storage platter, wherein the control circuit is further configured calculate multiple angles of movement in a specified direction for said single actuator arm, wherein said multiple angles of movement are associated with said first read/write data head and said second read/write data head with respect to reaching specified tracks on said data storage platter, wherein the control circuit is further configured to selectively enable or disable communications to said first read/write data head or said second read/write data head in response to a time associated with an angle of said multiple angles, and wherein said angle indicates which of said first read/write data head or said second read/write data head will reach a first track of said specified tracks on said data storage platter first.
