A magnetic tape reel that has a plurality of gear teeth capable of engaging with a plurality of engagement gear teeth provided with a reel engaging portion of a recording and reproducing apparatus and upon which magnetic tape can be wound, the magnetic tape reel comprising: a hub portion including a cylindrical portion upon which the magnetic tape can be wound and the plurality of gear teeth; and a positioning mark capable of being detected using a contactless detector, the positioning mark being provided for aligning a specific gear tooth A from the plurality of gear teeth with a specific engagement gear tooth B from the plurality of engagement gear teeth.

Magnetic tape reel having a positioning mark capable of being detected using a contactless detector, tape cartridge using the same, recording and reproducing apparatus for recording and reproducing information in the tape cartridge, and information recording and reproducing method thereof

A tape cartridge includes a case, a magnetic tape stored in the case, and a write protect structure for blocking information recording onto the magnetic tape, in which the write protect structure includes, for example, a slidable write protect member and a retention member (e.g., a guide wall) capable of retaining the write protect member in a specified position, and the retention member is capable of reversibly retaining the write protect member at least in a first position and a second position and irreversibly retaining the write protect member in a third position.

Magnetic tape cartridge with write protect member movable to irreversibly retaining position

A tape cartridge includes a case having a first through-hole and a second through-hole in the bottom of a first container, a reel disposed within the case and having a cylindrical hub portion with a bottom, a tape wound around the hub portion such that the tape can be fed out, and a reel lock mechanism that allows the reel to be immovably supported. The reel lock mechanism includes an interposing member that can move vertically in the thickness direction of the case, and a support member. The support member includes a first pedestal portion that, in a state in which the reel has been put in contact with the second container and the interposing member has been put in contact with the reel, is positioned immediately below the interposing member and thus immovably supports the interposing member; and an operating portion that is disposed in the first through-hole and allows, with a predetermined operation, support of the interposing member and release of support of the interposing member.

Tape cartridge and recording/reproducing apparatus

A tape cartridge according to the present invention includes a case, a reel disposed in the case, a tape that can be wound around the reel in such a manner as to be fed out freely, and a guide member for tape guidance disposed in the case. The guide member is supported by a support member, which is held at a predetermined position inside the case and supported by the reel without interfering with a rotation of the reel.

Tape cartridge

A recording medium built-in cartridge of the present invention includes: a case; a recording medium housed in the case; and at least one humidity control member disposed in the case and including at least one humidity control material that absorbs moisture in the case when a humidity in the case is a first humidity or higher and emits the moisture to the case when the humidity in the case is a second humidity or lower, the second humidity being lower than the first humidity.

Recording medium built-in cartridge and cartridge built-in package

A tape cartridge includes a case, a magnetic tape stored in the case, a movable member slidably or movably mounted on the case and having a display portion visible from an outside of the case, a plurality of management information sets about the tape cartridge are displayed on the display portion, and a plurality of the information sets include one or more information sets different from each other.

Tape cartridge with visible management information

There is provided a magnetic tape cartridge, including a cartridge () composed of a top cartridge () and a bottom cartridge (), a reel () rotatably disposed in the cartridge (), and a magnetic tape () wound onto the reel (), in which a width (w) of the magnetic tape () is over 12.65 mm, a thickness (h) of the cartridge () is 32 mm or less, and the width (w) of the magnetic tape is 60% to 90% of the thickness (h) of the cartridge ().

Magnetic tape cartridge

A single-reel tape cartridge cooperable with an operatively compatible tape drive including a tape catch member (H) includes a cartridge housing ( ) having a tape window ( ) defined therein and accommodating therein a single reel ( ) with a roll of a length of magnetic recording tape ( ) thereon. A leader pin ( ) is secured to a free end of the magnetic tape ( ) and engageable with the tape catch member (H) when the length of magnetic tape is to be drawn out of the cartridge housing and into the tape drive. A releasable locking mechanism for locking the leader pin ( ) in a predetermined posture at a retracted position at which the leader pin is housed within the cartridge housing ( ) and positioned adjacent the tape window ( ) includes a pair of first locking members ( ) and a second locking member ( ) cooperable with each other to lock the leader pin ( ) at a retracted position.

Single-reel tape cartridge with leader locking mechanism

A single-reel tape cartridge cooperable with an operatively compatible tape drive including a tape catch member ( ) includes a cartridge housing ( ) having a tape window ( ) defined therein and accommodating therein a single reel ( ) with a roll of a length of magnetic recording tape ( ) thereon. A leader member ( ) includes a metallic leader pin ( ) extending in a direction orthogonal to a lengthwise direction of the magnetic tape and first and second hooking arms ( ). The leader pin has opposite ends thereof insert-molded into the first and second hooking arms ( ) to thereby connect the leader pin with the first and second hooking arms ( ) so as to represent a generally U-shaped configuration.
