摘要： A recording tape cartridge includes a case, a shielding member, a first dustproofing wall portion and a second dustproofing wall portion. The case rotatably accommodates a single reel on which a recording tape is wound. An aperture is formed in a side wall of the case for drawing out of a leader member attached to an end portion of the recording tape. The shielding member slides along the side wall to open and close the aperture. The first dustproofing wall portion is provided protruding from a portion of the side wall, and the second dustproofing wall portion is provided protruding from the shielding member. When the aperture is closed, the first dustproofing wall portion opposes the shielding member and the second dustproofing wall portion contacts or is proximate to the first dustproofing wall portion.

摘要： A recording tape cartridge includes: a reel that includes a bottomed circular cylinder-shaped hub; a case that includes a top plate and a bottom plate, with the reel being singly housed in the case such that the reel is movable along an axial line direction between the top plate and the bottom plate; a ring-shaped member that is fixedly attached to the inner peripheral surface of the hub; an engagement gear formed on the ring-shaped member such that its teeth surface is substantially parallel to the axial line of the reel; and a brake member having a brake gear that is capable of meshing with the engagement gear. The brake gear, by being displaced in the axial line direction of the reel, can take a rotation lock position where the brake gear meshes with the engagement gear and a rotation allowance position where the meshing is released.

摘要： A tape drive assembly (20) for the transmission of data relative to a magnetic storage tape (278) includes a tape head (260), a cartridge receiver (268) and a controller (44). The cartridge receiver (268) selectively receives a cartridge (54) having a lapping tape (478) that laps the tape head (260). The controller (44) dynamically adjusts one of (i) a tension of the lapping tape (478) relative to the tape head (260), (ii) an oscillation frequency of the tape head (260) relative to the lapping tape (478), and (iii) a lateral velocity of the lapping tape (478) relative to the tape head (260). The controller (44) can use an algorithm to adjust these conditions. The algorithm can be based on the pliability of the lapping tape (478), a curvature of the tape head (260) and/or the grit of the lapping tape (478). In addition, or in the alternative, the algorithm can be based on at least one of an output of the tape head (260), a resolution of a signal from the tape head (260), an error rate in reading of data by the tape head (260) from the storage tape (278), an error rate in writing of data by the tape head (260) to the storage tape (278), and a signal-to-noise ratio from the tape head (260).

摘要： A recording tape cartridge includes a leader member that is attached to an end portion of recording tape and on both ends of which flange portions are formed, and holding portions that are formed in an upper case and a lower case and hold the leader member in the vicinity of an opening. Projecting portions are formed on the holding portions and overlap the flange portions on inner surface sides of the flange portions. Through holes are formed in the upper case and the lower case, whereby undercut portions are not present in the projecting portions. The case of the recording tape cartridge can be molded without complicating the configuration of the mold.

摘要： In a single-reel type tape cartridge of a servo tracking system in which signal recording is performed, a tape reel capable of eliminating edge projection during tape winding and achieving high recording density of a magnetic tape and a magnetic tape cartridge for housing the tape reel is provided. The tape reel is provided with a cylindrical hub around which the magnetic tape is wound and a pair of upper and lower flanges. The average value of the thickness of a reference flange that receives the tape edge of the magnetic tape during tape winding is set greater than the average value of the thickness of the opposite flange. The tape receiving surface of the reference flange is formed into an inclined surface, and three or more air escape recess portions are formed on the tape receiving surface. The depth of each air escape recess portion is set not smaller than 0.05 mm and not greater than 0.40 mm. The occupation area of all the air escape recess portions is set to 30% to 80% of the total area of the reference flange. Such tape reel is housed in a magnetic tape cartridge.
