inodyn NewMedia Assigned Patent

inodyn NewMedia GmbH, Neckargemuend, Germany, has been assigned a patent (9,431,056) developed by Pantel, Lothar, Neckargemuend, Germany, for a “selective shingled magnetic recording scheme.“

The abstract of the patent published by the U.S. Patent and Trademark Office states: “A selective band management scheme for storage devices is disclosed that may be used in connection with shingled magnetic recording, (SMR). SMR uses bands consisting of tracks separated by guard regions. The replacement of a defective sector may be attained by selecting a suitable guard region and by displacing the selected guard region onto the physical location of the defective sector. The boundaries of the bands may be shifted. The portion of the disk surface that is necessary for the guard regions may simultaneously function as a spare sector area for defective sectors without additional space requirements. In at least one embodiment, guard regions are selectively placed onto tracks with an elevated number of primary defects by means of an optimization algorithm.“

The patent application was filed on February 2, 2016 (15/013,868).
