  • Patent number: 11295771
    Abstract: The present disclosure generally relates to a head positioning assembly in a tape embedded drive. The tape embedded drive has two reels as well as four guide rollers. The reels and guide rollers are arranged within the tape embedded drive so as to position the head positioning assembly as close to the center of the tape embedded drive as possible. In so doing, the reels, guide rollers, and head assembly are more stable which reduces or even eliminates shock and vibration to the tape embedded drive.

  • Patent number: 7938235
    Abstract: A brake includes a braking portion for braking a rotatable element, a swinging portion secured with the braking portion, a resilient portion integrally formed with the swinging portion for generating a restoring force to make the braking portion contact the rotatable element, and a forced portion for being operated to counteract the restoring force and rotate the braking portion via the swinging portion. When the forced portion is acted, the resilient portion is compressed and the braking portion is driven to separate from the rotatable element, and when the forced portion is free, the resilient portion restores to drive the braking portion to contact with the rotatable element.

  • Patent number: 7163172
    Abstract: A reel driving device includes a reel stand for driving a reel to rotate; and a latch including at least one contact portion contactable with the reel. The reel stand includes a convexed and concaved portion. The latch includes a claw portion for, when contacting the convexed and concaved portion, stopping a rotation of the convexed and concaved portion. While the reel stand rotates in a first direction, the latch moves in such a direction that the claw portion contacts the convexed and concaved portion by a rotation of the reel stand being conveyed to the at least one contact portion. While the reel stand rotates in a second direction, the latch moves in such a direction that the claw portion is separated from the convexed and concaved portion by a rotation of the reel stand being conveyed to the at least one contact portion.

  • Patent number: 7140570
    Abstract: Disclosed are a reel brake device and a magnetic recording and reproducing apparatus having the same. The reel brake device comprises a tension band mounted on an outer circumference of a reel disc to control tension, the reel disc which is rotatably mounted on the main chassis to drive a tape reel of a tape cassette, and a brake unit fixed on the main chassis to help the tension band be in contact with the outer circumference of the reel disc. This can replace a conventional brake unit having a complicated structure, and therefore, the number of component parts can be reduced.

  • Publication number: 20040069889
    Abstract: A reel brake assembly for a magnetic recording/reading apparatus comprises a sub-deck slidably disposed on a main-deck in which a head drum is mounted, a reel table rotatably disposed in the sub-deck, for selectively driving a tape reel of a tape cassette, a brake unit pivotably disposed on the sub-deck, for selectively braking the reel table, and a cam gear rotated by a driving force of a driving motor, for moving the sub-deck to load and unload the sub-deck. The brake unit is selectively brought into contact with and separated from the reel table in relation to movement of the cam gear when the sub-deck is loaded and unloaded.

  • Patent number: 6536695
    Abstract: A magnetic tape apparatus includes a pair of reel tables adapted to be detachably engaged with a tape cassette and rotatably disposed on a chassis with a determined space therebetween, and a pair of brake members which are adapted to be press-contacted and separated with respect to the reel tables by way of brake pads. Each of the brake members is provided with a projection at one end portion of a tip end face thereof and a recess adjacent to the other end portion of the tip end face. Each of the brake pads is provided with a slit at its one end portion, the slit being engaged with the projection, and the other end portion of the brake pad being pushed into the recess.

  • Publication number: 20020166913
    Abstract: A data storage tape cartridge including a housing, a tape reel assembly, a brake assembly, a centering device, and a storage tape. The tape reel assembly includes a hub, opposing top and bottom flanges, and drive teeth. The drive teeth extend in an axial fashion relative to the hub and are provided for engagement by a tape drive chuck. The centering device is provided to support the tape reel assembly in a centered position relative to the tape reel opening in the locked state. The centering device includes a rib and a corresponding groove. The rib is formed by one of the bottom flange and the base, whereas the groove is formed by another of the bottom flange and the base. The groove is configured to selectively receive the rib, thereby supporting the tape reel assembly in the center position. The centering device prevents the tape reel assembly from laterally shifting relative to the tape reel opening when the data storage tape cartridge is vertically oriented.
