Patent number: 12106772Abstract: The present disclosure generally relates to increasing storage capacity for magnetic media dual-reel tape devices, and more specifically modifying the writing process to the magnetic media. Rather than having an unused acceleration zone, portions or even the entire acceleration zone on the tape can be used to store data. To achieve the acceleration to a predetermined speed, the tape is wound in the opposite direction from where the writing and/or reading will occur. The winding is of a sufficient distance to create sufficient distance along the tape for the acceleration to the predetermined speed to be completed by the time the writing and/or reading location is reached. Furthermore, when the acceleration zone is completely used for data, writing can occur from the beginning of the tape to the end of the tape rather than writing to/from the acceleration zone and then returning to a corresponding end of the tape.Type: GrantFiled: July 19, 2023Date of Patent: October 1, 2024Assignee: Western Digital Technologies, Inc.Inventors: Keiichi Okada, Akira Sakagami, Takehiko Hamaguchi

Patent number: 8736909Abstract: According to an aspect of the invention, an image forming apparatus includes an image correction unit and a determination unit. The image correction unit inserts a new pixel between pixels forming image data with a plurality of pixels printed using a plurality of print color materials arranged in a main scanning direction in order to correct the image width in the main scanning direction. The determination unit determines whether or not the image data is specified for print with a dot representing given information superposed. When the determination unit determines that the image data is specified for print with the dot superposed, a prohibition unit included in the image correction unit prohibits insertion of the new pixel into a pixel string of a print color material of a similar color to the print color material for the dot.Type: GrantFiled: May 18, 2010Date of Patent: May 27, 2014Assignee: Fuji Xerox Co., Ltd.Inventors: Noribumi Sato, Mitsuru Iioka, Jun Koyatsu, Kaoru Yamauchi, Keiichi Okada
