A tape end sticking apparatus sticking a tape end of a tape strip on a reel hub of a tape reel installed in a cartridge case having an egress/ingress opening before winding the tape strip onto the reel hub is described. The tape end sticking apparatus includes a tape carrier for grasping a tape end portion and bringing the tape end portion in close proximity to the reel hub which is movable into and out from a tape cartridge case through a cartridge opening and a liquid applying device for applying a sticking liquid to the reel hub and/or the tape end portion in a spread pattern having a width smaller at a remotest end than a foremost end thereof when the tape end sticking apparatus brings the tape end portion in close proximity to the reel hub.

A metal plate of a recording tape cartridge is provided with a tapered portion at an outer circumference thereof. In a state in which the metal plate is attached at a fixed-side mold plate of a metal mold for molding a reel hub and a lower flange, a gap is formed between the tapered portion and the fixed-side mold plate. During molding, molding material flows into the gap. Because of this gap, an annular pawl portion is formed at the reel hub, which annular pawl portion integrally joins the metal plate with the reel hub by sandwiching the metal plate via the tapered portion.

The invention provides a recording tape attaching method and a recording tape attaching apparatus for accurately attaching a recording tape to a reel hub. In the method and the apparatus for winding a recording tape around a hub of a reel, a hub is contacted with a recording tape retained by suction by a retaining member and rotated, thereby generating static electricity, and the recording tape is attached to the hub by attracting the recording tape to the hub by the generated static electricity.

A normal tape reel is disclosed, comprising a tape reel portion and a magnetic tape wound on the reel core of the tape reel portion, wherein the ratio of the winding radius R of the magnetic tape to the radius r of the reel core (R/r) is not smaller than 3.5 and the winding hardness of the magnetic tape is adjusted to a range of from 1.9 to 11.5 N.

A molding mold and a molding method are disclosed, for molding a flange configuration in which a flange of a reel hub portion can be maintained in a predetermined configuration. Also a tape cartridge is disclosed, which can securely prevent a tape-shaped recording medium from touching at the flange while the tape cartridge is being used. In the molding mold for molding, a flange configuration is produced, which is provided with a reel hub portion having a flange and a hub arranged at a substantially center of the flange and an insert portion disposed at a substantially center of the reel hub portion at an opposite side of the hub, and which includes: an insert attaching portion; a flange forming portion for forming the flange; and a hub forming portion for forming the hub; wherein in a forming surface of at a side of the hub forming portion of the flange forming portion, a dimension of a circular area over from a root end of the hub forming portion to a substantially intermediate portion between the root end and a circumferential end of the flange forming portion, is corrected in view of deformation upon molding.

A magnetic tape cartridge comprises: a reel 2 around which a magnetic tape MT is wound; a cartridge case 1 for accommodating the reel 2 in a locked state; and a release pad 5 inserted into a cup-shaped hub 2A of the reel 2 in a locked state of the reel 2. The release pad 5 includes a pad body 5A having a plurality of corners to be faced proximately to the inner peripheral surface 2C of the cup-shaped hub 2A, and a plurality of lock releasing pins 5B projecting downwardly from a bottom surface of the pad body 5A at the respective corners and inserted through a bottom surface of the cup-shaped hub 2A. The release pad 5 is provided with a flank 5E extending from each corner downwardly through the respective lock release pin 5B so that an assembling clearance is formed with respect to an inner periphery of a flange 2G position in an open side of the cup-shaped hub 2A.

A lower half (102) and an upper half (103) are plastic components having thermoplasticity. A welding head (1) having a plurality of convex portions formed in a circumferential direction, the convex portions extending in a longitudinal direction within a range of a predetermined length, is inserted so as to span a lower boss (107) and an upper boss (110) in a joint portion (105). The plastic in the joint portion (105) is melted by means of the welding head (1). The lower half (102) and the upper half (103) are welded to and integrated with each other by solidifying the molten plastic.

A magnetic tape cassette includes a case that is formed by joining an upper half and a lower half, one or more tape reels, a window and a reel urging member having a tape reel contacting portion which contacts an upper part of the tape reel(s), bent arms connected to opposite sides of the tape reel contacting portion and sliding end portions provided at distal ends of the bent arm. A slide groove is provided in an inner surface of a perimeter of a window opening in the upper half and a window member has hold-and-retain portions which hold the sliding end portions in cooperation with a bottom surface of the slide groove into which the sliding end portions have been fitted. A tape reel suitable for use with the magnetic tape cassette, a resinous leaf spring and its production process are also provided. Tape reels housed in a cassette case can be urged toward the lower half by a member whose structure is simple and permits easy fitting and removal. Assorted collection of constituent materials, particularly for assorted collection of resin materials and selective collection of resin materials as separate from metal materials are possible.

The tape cut-out apparatus, having: a control unit for storing a defect positional information showing a position of a defective portion of magnetic tape and, for outputting a predetermined winding length in accordance with the defect positional information; a winding device for drawing out the magnetic tape by an input predetermined winding length, winding it onto a reel and cutting it, and detecting a winding length to the reel and outputting the winding length to the control unit; and, a correcting unit for correcting the input predetermined winding length according to an accuracy of detecting the winding length of the winding device, and correcting an actually measured winding length when the magnetic tape is wound according to an accuracy of detecting the winding length and for outputting the corrected value of the actually measured winding length to the control unit.

In one example of one aspect of the invention, a data storage cartridge is provided. The data storage cartridge includes a housing having at least one opening, a reel rotatably disposed within the housing and accessible through the opening, the reel capable of translating axially, a biasing member for biasing the reel toward the opening, and an absorbing member disposed between the reel and a portion of the housing opposite the opening. In one example, the absorbing member includes a spring constant value of greater than 30 ounces per inch. The absorbing member may be disposed to engage and dampen the motion of the reel when the reel is displaced beyond a desired distance.
