Data storage

A data access method comprising:

• providing a data storage apparatus comprising a mounting structure, a first motor mechanically attached to said mounting structure, a data storage platter mechanically attached to said first motor, an actuator motor mechanically attached to said mounting structure, a single actuator arm mechanically attached to said actuator motor, and a control circuit, wherein said 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 data storage portion comprises data within a top surface of data storage platter, wherein said data storage portion comprises sections within said top surface, wherein said spindle portion is located within a center of a rotation portion 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;
• moving axially, by said actuator motor, said single actuator arm along an arc and across said top surface of said data storage platter during rotation of said data storage platter;
• accessing, by said first read/write data head in response to said moving axially, said first section and said second section;
• accessing, by said second read/write data head in response to said moving axially, only said second section;
• and
• controlling, by said control circuit, communications to said first read/write data head and said second read/write data head, wherein said controlling comprises:
• selectively enabling or disabling 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;
• calculating 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;
• and
• selectively enabling or disabling 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, 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.

A computer program product, comprising a computer readable storage device storing a computer readable program code, said computer readable program code comprising an algorithm that when executed by a computer processor of a data storage apparatus implements a method, said data storage apparatus comprising a mounting structure, a first motor mechanically attached to said mounting structure, a data storage platter mechanically attached to said first motor, an actuator motor mechanically attached to said mounting structure, a single actuator arm mechanically attached to said actuator motor, and a control circuit, said method comprising:

• moving axially, by said actuator motor, said single actuator arm along an arc and across a top surface of said data storage platter during rotation of said data storage platter, wherein said 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 data storage portion comprises data within a top surface of data storage platter, wherein said data storage portion comprises sections within said top surface, wherein said spindle portion is located within a center of a rotation portion 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;
• accessing, by said first read/write data head in response to said moving axially, said first section and said second section;
• accessing, by said second read/write data head in response to said moving axially, only said second section;
• and
• controlling, by said control circuit, communications to said first read/write data head and said second read/write data head, wherein said controlling comprises:
• selectively enabling or disabling 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;
• calculating 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;
• and
• selectively enabling or disabling 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, 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.
