摘要： PROBLEM TO BE SOLVED: To provide a tape cartridge by which a magnetic tape is appropriately wound to a reel by suppressing a tape damage such as pressure.
SOLUTION: In the tape cartridge C in which one end part of a tape LT is locked to a clamp mechanism 62 arranged inside a reel hub 51 via a slit 56 formed on the peripheral surface of the reel hub 51, at least a wall part in front of the tape winding direction among a pair of opposite wall parts constituting the slit 56 is formed aslant (an angle α) toward the tape winding direction to a reel radial direction shaft (A-A). By such structure, the tape LT drawn out from the slit 56 is smoothly wound along a circular arc on the peripheral surface of the reel hub 51, pressure or winding disorder is prevented to protect the tape.

摘要： PROBLEM TO BE SOLVED: To provide a tape cartridge in which high speed running stability of a magnetic tape is improved, high recording capacity is attained, and sufficient durability for drop, impact, or the like can be secured.
SOLUTION: It is suppressed that the width size of a cartridge case is increased even if a reel diameter is increased due to increment of tape winding length by arranging a pair of reels 24 on a diagonal of a cartridge case 21. Also, useless vibration of a tape drive system in a high rotation number region is suppressed by rotating a pair of reels 24 respectively in a reverse direction and travelling a magnetic tape 29, stable rotation attitude of the reels and high speed running of the tape are secured. And durability for drop, impact, or the like is improved by constituting so that an opening 21W for loading is made a single opening formed at a front wall part 21F of the cartridge case and a shutter 27 shutting and closing this opening is slide-moved.

摘要： PROBLEM TO BE SOLVED: To provide a tape reel in which flowing out of melted resin to a circumferential surface of a reel hub can be prevented while sufficient welding strength is secured, and a tape cartridge with it.
SOLUTION: Melted resin 43m of a welding rib 43c melted in ultrasonic welding is collected at a concave part 43f formed around the welding rib 43c formed at a welding plane 43b of an upper reel 43, and flowing out of melted resin 43m to a circumferential surface of a reel hub 41 is prevented. Thereby, flatness of the reel hub circumferential surface 41c can be secured, and a magnetic tape can be wound appropriately. Also, since flowing out of melted resin 43m can be prevented independently of the size of the welding rib 43c, the welding rib 43c can be formed so as to obtain sufficient welding strength.

摘要： PROBLEM TO BE SOLVED: To improve alignment by effectively suppressing the inversion of a magnetic field direction when the alignment of magnetic bodies in magnetic paint is controlled. SOLUTION: A magnetic coating 2 is formed by applying the magnetic paint on a nonmagnetic base 1A and particles of the magnetic powder incorporated in the magnetic coating 2 are aligned through a magnetic field. Permanent magnets 20A and 20B and a solenoid coil part 30 are arranged in order in a feed path for the nonmagnetic base 1A with the magnetic coating 2 to apply a magnetic force. The permanent magnets 20A and 20B give smaller magnetic forces than the solenoid coil 30A and the solenoid coil 30A and permanent magnets 20A and 20B are arranged having their poles of the same polarity side by side. Further, the permanent magnets 20A and 20B are arranged at positions included in the magnetic field of the solenoid coil 30A. Such arrangement optimizes the state of a magnetic force outside the solenoid coil 30A to obtain excellent alignment.
