  • Storage controllers and storage control methods
    Patent number: 9268709
    Abstract: According to various embodiments, a storage controller configured to control storage of data in a pre-determined area of a storage medium may be provided. The storage controller may include a memory configured to store a write pointer, a reclaim pointer, and a wrapped around pointer. The write pointer may indicate a location of the storage medium to write incoming data. The reclaim pointer may indicate a location of the storage medium to perform a space reclamation. The wrapped around pointer may indicate a location of the storage medium where writing is to continue if writing of data reaches an end of the pre-determined area.

  • Data storage device
    Patent number: 9202512
    Abstract: According to an embodiment of the present invention, a data storage device comprising a motor having a stator is disclosed. The stator may include a substrate having a first surface and a second surface opposite to the first surface; and a n-phase winding arrangement having n phase windings; wherein each phase winding comprises m flat fractional-pitch coils arranged on the first surface of the substrate such that the coils are spaced apart uniformly along a closed loop and connected in series; wherein each coil together with an angular section of the substrate between the coil and an adjacent coil of the same phase winding defines a stator pole-pair; and wherein m is an integer larger than 1.
