Patent number: 9928856Abstract: A magnetic storage system according to one embodiment includes a magnetic head having a removable organic coating thereon in an amount sufficient for reducing exposure of the head to oxidation promoting materials. The system also includes an applicator in a drive in which the magnetic head resides, the applicator being configured to apply the organic coating directly to the magnetic head without contacting the magnetic head. At least one guide is configured to create a spacing between the magnetic head and the guide, wherein the spacing is sufficient to insert the applicator into the spacing.Type: GrantFiled: April 15, 2016Date of Patent: March 27, 2018Assignee: International Business Machines CorporationInventors: Richard Lionel Bradshaw, Icko Eric Timothy Iben, Wayne Alan McKinley, Lee Curtis Randall

Patent number: 8465855Abstract: Encapsulated particles and methods for manufacturing encapsulated particles and structures are described. Such particles may have a length no greater than 40 nm, and include at least one material selected from the group consisting of ferromagnetic materials and ferrimagnetic materials. A polymeric encapsulant surrounds the particle, the polymeric encapsulant including a phase-separated block copolymer including a glassy first phase and a rubbery second phase, the glassy first phase positioned between the particle and the second rubbery phase. The glassy first phase includes a hydrophobic copolymer having a glass transition temperature of at least 50° C. The rubbery second phase includes a polymer having at least one of (i) a glass transition temperature of no greater than 30° C., and (ii) a tan delta peak maximum of no greater than 30° C.

Patent number: 6890631Abstract: A flexible magnetic-tape substrate is coated on both sides with an underlayer of relatively-low coercivity magnetic medium, which in turn is coated with a submicron layer of chromium dioxide in ultra small particles having a high coercivity. For longitudinal magnetic recording systems, magnetic layers with a coercivity of at least 1,500 Oe with underlayers having a coercivity between 25 and 500 Oe are used. For helical magnetic recording systems, magnetic layers with a coercivity of at least 2,000 Oe with underlayers having a coercivity between 25 and 800 Oe are used. These properties greatly reduce the effects of neighboring magnetic fields, thereby improving signal retention and virtually eliminating print-through and contact recording.Type: GrantFiled: June 10, 2002Date of Patent: May 10, 2005Assignee: International Business Machines CorporationInventor: Richard Lionel Bradshaw
