Patent number: 8318242Abstract: A method in one embodiment includes applying an organic coating to a magnetic head for reducing exposure of the head to oxidation promoting materials; and storing the magnetic head. A method in another embodiment includes applying an organic coating to a magnetic head for reducing exposure of the head to oxidation promoting materials, the organic coating being applied to the magnetic head after the head is installed in the magnetic storage system. Another method includes fabricating a tape having an applicator portion for applying an organic coating to a magnetic head for reducing exposure of the head to oxidation promoting materials; applying the organic coating to the applicator portion of the tape; and applying a lubricant to a data portion of the tape. A method in another embodiment includes fabricating a tape having a data portion, and a cleaning portion for removing an organic coating from a magnetic head.Type: GrantFiled: May 5, 2008Date of Patent: November 27, 2012Assignee: International Business Machines CorporationInventors: Richard Lionel Bradshaw, Icko E.

Publication number: 20110076782Abstract: Embodiments of the invention relate to magnetizing and detecting nanoparticle-labeled antigens on biosample tracks deposited on a tape media. An aspect of the invention comprises apparatus and methods for labeling antigens with demagnetized nanoparticles, magnetizing the nanoparticles with an electromagnetic write head, and detecting the antigens via the magnetized nanoparticles by reading the tape media with a read sensor in a read-after-write operation. The write head and read sensor are part of a head-module of magnetic tape drive. Target antigens are attached to the biosample tracks by antibodies. Nanoparticles of differing magnetic properties may be selectively paired with antibodies associated with different antigens to allow multiple antigens to be detected upon a single scan by the read sensor.Type: ApplicationFiled: September 22, 2010Publication date: March 31, 2011Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Tara L. Awezec, Dylan Joseph Boday, Lee Curtis Randall, Stephen Leonard Schwartz, Anna W. Topol, Daniel James Winarski

Publication number: 20110076670Abstract: A first set of antibodies are bonded to a substrate, and are exposed to and bonded with target antigens. A second set of antibodies are bonded to nanoparticles, and the nanoparticle labeled antibodies are exposed to the targeted antigens. An electromagnetic write-head magnetizes the nanoparticles, and then a read-sensor detects the freshly magnetized nanoparticles. The substrate comprises a flexible film or a Peltier material to allow selective heating and cooling of the antigens and antibodies. Nanoparticles of different magnetic properties may be selectively paired with antibodies associated with different antigens to allow different antigens to be detected upon a single scan by the read-sensor.Type: ApplicationFiled: September 22, 2010Publication date: March 31, 2011Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Dylan Joseph Boday, Lee Curtis Randall, Stephen Leonard Schwartz, Anna W. Topol, Daniel James Winarski

Publication number: 20110077869Abstract: A circuit for detecting antigens on biosample tracks comprising a processor, an electromagnetic write head for magnetizing nanoparticles attached to the antigens via antibodies in response to a write signal from the processor, and a first amplifier for supplying power to the write head. The circuit further comprises a magneto-resistive read sensor for detecting the magnetized nanoparticles upon receiving a read signal from the processor, and a second amplifier for supplying power to the read sensor. The write head and read sensor may be part of a head module in a magnetic tape drive. Nanoparticles of differing magnetic properties may be selectively paired with antibodies associated with different antigens to allow different antigens to be detected upon a single scan by the read-sensor.Type: ApplicationFiled: September 22, 2010Publication date: March 31, 2011Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Dylan Joseph Boday, Louie Arthur Dickens, Steven Mark Groff, Icko Eric Timothy Iben, Wayne Alan McKinley, Lee Curtis Randall, Stephen Leonard Schwartz, Anna W.

Patent number: 7656602Abstract: A method for protecting a magnetic head according to one embodiment includes reducing a relative humidity in a vicinity of a magnetic head by passing an elevated bias current through a sensor of the head during at least some time periods when the sensor is not in use for reading data, the elevated bias current being chosen to be sufficient to heat the sensor to a level which will reduce the local relative humidity to below a threshold level for reducing or eliminating corrosion of the sensor. Additional methods are also presented.Type: GrantFiled: July 1, 2008Date of Patent: February 2, 2010Assignee: International Business Machines CorporationInventors: Icko E.

Patent number: 7430799Abstract: A method for preforming of two or more flexible cables in an arrangement consisting of a combination of rigid printed circuit boards and flexible cable sections extending therebetween. Moreover, also provided is an apparatus for the preforming of two or more flexible cable sections of a combination of rigid printed circuit boards and therewith interposed flexible cable sections which are adapted to interconnect the rigid printed circuit boards. The apparatus consists of a tool constituted of an elongated cylindrical member having a tapered leading end which narrows into an ultra-thin flat end section of a blade-like configuration, and which is adapted to be pushed between the flexible cables and so as to preform the flexible cable sections and cause them to yield in a predetermined outwardly bowed permanently relationship between the rigid printed circuit boards at the opposite ends thereof to lengthen the fatigue life of the conductors in the flexible cable sections.Type: GrantFiled: December 29, 2004Date of Patent: October 7, 2008Assignee: International Business Machines CorporationInventors: Lee Curtis Randall, Thomas Stanley Truman, Daniel James Winarski, George G. Zamora

Patent number: 6744592Abstract: A strip with an exterior sticky surface is judiciously selected for its ability to entrap dust and other loose debris without interfering with the operation of moving parts contacted thereby. The strip is attached to the sides of a magnetic tape cartridge, with the sticky surface facing outward, in places contacted by rollers and/or belts during the process of handling the cartridge in an automated system. Thus, any loose debris in the rollers or belts is retained by the tacky surface of the strip as the cartridge passes through the rollers and belts of the robotic system. The strips of the invention may be removably adhered to the data cartridge, or may be permanently attached. In a particular embodiment of the invention, the strips may be incorporated into a cleaner cartridge for the periodic maintenance of loading equipment.Type: GrantFiled: June 3, 2003Date of Patent: June 1, 2004Assignee: International Business Machines CorporationInventor: Lee Curtis Randall

Patent number: 6676026Abstract: A data storage and retrieval system such as a robotic library has a large plurality of removable storage media, such as tape cartridges, for purposes of I/O. To enhance performance and reliability of the library, a thermodynamic model of the library is constructed and stored in the library, and environmental conditions such as the temperature, humidity, and flow rate of cooling air coming into, flowing through, and leaving the library are monitored. The thermodynamic model of the library includes an acceptable operating range for the library in a psychrometric chart; and the product of the effective thermodynamic mass and specific heat of the library.Type: GrantFiled: August 7, 2002Date of Patent: January 13, 2004Assignee: International Business Machines CorporationInventors: Wayne Alan McKinley, Lee Curtis Randall, Daniel James Winarski
