摘要: A tape drive (226) for use in a tape library (10) that retains at least one tape cartridge (220) that retains magnetic tape (250) includes a drive housing (226A) and a media conditioner (255). The drive housing (226A) is configured to receive the tape cartridge (220). The media conditioner (255) is coupled to the drive housing (226A). The media conditioner (255) is configured to condition the magnetic tape (250) when the tape cartridge (220) is received within the drive housing (226A). The media conditioner (255) can be configured to remove at least one of abrasives, contaminants and lubricants that are on the magnetic tape (250) when the tape cartridge (220) is received within the drive housing (226A). The magnetic tape (250) is configured to move along a predefined path (251) within the drive housing (226A), which is defined by one or more rollers (254). The rollers (254) can include a modified roller (270) having a roller body (274) and an outer coating (276) that is affixed on an outer surface (274A) of the roller body (274). The media conditioner (255) can include the modified roller (270).

摘要: In order to reduce the possibility of occurrence of retraction of a cleaning member during cleaning of a magnetic head and the possibility of the cleaning member not being able to return to a retraction position due to stopping part way, the cleaning enabling device is provided with: a holding member having a first surface capable of holding the cleaning member for cleaning the magnetic head, and a second surface capable of lifting a magnetic tape from the magnetic head; a transmission part which transmits a first driving force for driving a first driving member; and a first force application part which applies, to the holding member, a first force in a direction that causes the cleaning member to remain in the retraction position when the cleaning member is in the retraction position and releases the first force when the cleaning member is drawn away from the retraction position.

摘要: An example cleaning card for cleaning a check-reading machine can include at least two opposing surfaces. The opposing surfaces can include a cleaning feature configured to clean at least one component of the check-reading machine when the cleaning card is fed through the check-reading machine. An ink can be located on at least one of the opposing surfaces. The ink can define a set of Magnetic Ink Character Recognition (MICR) characters capable of identifying the cleaning card. The position of the set of MICR characters can coincide with a routing field of the cleaning card as defined in accordance with the standard of the American National Standards Institute (ANSI) X9 family of standards. Other systems, apparatuses, and methods are also described.

摘要: Provided herein is a magnetic write head including a near field transducer and a magnetic recording media including a media lubricant. The media lubricant includes a first portion and a second portion. The second portion of the media lubricant is evaporated in response to heat emitted from the near field transducer. The second portion of the media lubricant that is evaporated removes a contaminant over the near field transducer.

摘要: A diagnostic tape (318) for use with a tape drive (310) having a tape head (322) includes a first tape section (430A) and a second tape section (430B). The first tape section (430A) and the second tape section (430B) are configured to move across the tape head (322) during use of the tape drive (310). The first tape section (430A) includes a first patterned data code (432A) that is indicative of a first spacing between the tape head (322) and the first tape section (430A). The second tape section (430B) includes a second patterned data code (432B) that is indicative of a second spacing between the tape head (322) and the second tape section (430B). The second patterned data code (432B) is different than the first patterned data code (432A). The diagnostic tape (318) can further include a tape head cleaning section (630F) including abrasive material (650) that is configured to move across the tape head (322) to clean the tape head (322).

摘要: In one general embodiment, an apparatus includes a magnetic tunnel junction device having a reference layer, a free layer, and a tunnel barrier layer between the free and reference layers. The tunnel barrier layer is primarily crystalline alumina. In another general embodiment, a method includes forming a first magnetic layer, forming a tunnel barrier layer above the first magnetic layer, and forming a second magnetic layer above the tunnel barrier layer. The tunnel barrier layer includes crystalline alumina. The tunnel barrier layer is formed at a temperature of less than 100 degrees centigrade.
