A tape cartridge is provided with reliable reel lock and motor / reel coupling mechanisms whose functions are both accomplished during a single motion of the cartridge relative to the drive motor. The motor / reel coupling includes a circular set of gear teeth on the bottom of the tape reel which meshes with a complementary set of gear teeth on a motor coupling rotated by the motor when the cartridge is loaded into the tape drive and the cartridge and motor are moved towards each other. An engagement force to maintain the coupling is provided by an engagement spring in the cartridge which biases the reel towards the motor. Reel locking is accomplished by providing a second circular set of gear teeth on a top side of the tape reel which meshes with a complementary set of gear teeth provided on a slidably mounted locking bracket inside the tape cartridge. A lock spring normally biases the locking bracket towards the top of the tape reel, thus locking the reel when the cartridge is not engaged with the motor. When the cartridge and the drive motor are moved towards each other, the motor coupling engages the bottom of the tape reel, and a projection on the motor coupling extends into the tape cartridge to slide the locking bracket out of engagement with the teeth on the top of the tape reel, thereby unlocking the reel. Thus, reel unlocking and motor / reel coupling are accomplished with a single motion by reliable mechanisms.

The method and unit for braking a metal strip (1), running off a wind-out coiler (2.1) in the form of a coil (1.1) and running onto a wind-on coiler (2.2) again, are to guarantee that a surface of the metal strip remains undamaged and a full effective braking force is exerted on the metal strip (1) by means of an eddy current brake (3.1) with a rotating magnet system (3.2). The above is achieved, whereby the braking force is exerted on the metal strip (1) by means of an induced counter-torque against a support bearing (4) to one side in a non-contact manner, whereby the support bearing (4) may be embodied as a counter roller (4.1).

A lockable chain winder for opening and closing windows has an internal mechanism which includes a stop member (16) which can be moved to engage with the chain winder sprocket (15) in such a manner that the sprocket (15) can freely rotate on one direction, but not in the other direction.

A wind-up type storage container is provided that can easily wind up and store a small or large item, such as a bag, a flag, a sheet, rainwear, etc. and from which such items can be easily pulled out. In order to pull in an item to be stored, a button is pressed to move a wind-up shaft downwardly. A pawl receiving portion is engaged with engaging pawls, and a reel portion is interlocked with a winding shaft. When a reel cord is pulled out, the reel portion is rotated, and the item to be stored is pulled to and wound around a winding shaft. When the button is released, the reel cord is rewound by a restoring force of a power spring. The reel cord is repetitively pulled until the item to be stored is completely stored in the main body capsule.

A recording / reproducing method and a recording / reproducing apparatus for magnetic tapes are provided as a recording / reproducing technique suitable for recording density enhancement of magnetic tapes. The method and apparatus are capable of correctly recording and reproducing data without causing errors even with occurrence of size changes in the widthwise direction of a magnetic tape. In the recording / reproducing method for magnetic tapes in which data tracks and servo tracks are provided, a tape width is detected and a value of the tape width is stored during data recording, and data reproduction is performed while tape tension is controlled so that the tape width during data reproduction is maintained equal to the tape width during data recording.

A tape drive comprising two motors, two tape spool supports on which spools of tape may be mounted, each spool being drivable by a respective one of the motors, and a controller. The controller controls the energization of the motors such that the tape may be transported in at least one direction between spools mounted on the spool supports. The controller is configured to store a plurality of motor control data items, each data item being associated with a respective tension value. The controller is operative to monitor tension in a tape being transported between spools mounted on the spool supports; read a motor control data item based upon the monitored tension; generate a motor control signal based upon the read motor control data item; and apply the motor control signal to at least one of the motors.

A tape drive, tape drive recording system, and method are provided for improving tape speed selection during data transfer. The tape drive comprises a buffer, a tape for recording the data to be temporarily stored in the buffer, and a read head. The tape drive further comprises a reading controller that initially sets a tape speed such that a drive transfer rate matches a host transfer rate as closely as possible and that drives the tape at the tape speed. To address backhitching caused by one or more host transfer halts, the reading controller subsequently adjusts the tape speed such that the drive transfer rate is lower than the host transfer rate by recalculating the host transfer rate in consideration of the host transfer and the host transfer halt and setting the tape speed such that the drive transfer rate matches the recalculated host transfer rate as closely as possible.
