The invention proposes a tape drive apparatus, tape extraction apparatus and tape cartridge that enable a reliable chucking and chucking release, and a stable carrying of a tape being extracted from a cartridge. The invention is constituted by a magnetically recording/reproducing apparatus; a cartridge mount mechanismwhereon a tape cartridgewith the magnetic tape T wound therein is mounted; a takeup reelto wind up magnetic T thereon; a leader blockattached to one end of the magnetic tape T with a rotation restriction section provided thereon; a chucking mechanismwhich comprises a chucking pinthat restricts the rotation of the leader block and chucks the leader block, chucking and releasing chucking of the leader block; a carrying mechanismwhich comprises the carrying sectionfor carrying the chucked leader block; a chucking release leversandwhich releases chucking of the chucking mechanism, which is actuated by camsandprovided on the carrying sectionand disposed on both ends of the cam groovefor guiding the movement of the leader block; and reel motorsC andT including frequency generatorsC andT for rotationally driving the tape reelwithin the tape cartridgeand the takeup reel, respectively.

Tape drive apparatus, tape extraction apparatus and tape cassette

A tape drive apparatus, tape extraction apparatus and tape cartridge that enable a reliable chucking and chucking release, and a stable carrying of a tape being extracted from a cartridge. The apparatus includes a carrying mechanism for extracting the tape as a recording medium from the cartridge where the magnetic tape is stored, and for carrying the magnetic tape to be wound up onto a takeup reel provided on the drive apparatus.

Tape drive device, tape extraction device and tape cassette

This invention is directed to a tape cassette in which a tape body is wound across a pair of tape reels rotatably supported by the cassette body. At the cassette body, there are provided a first write protect mechanism provided in correspondence with the position where there is provided a write protect mechanism provided at other tape cassette loaded with compatibility with respect to a recording/reproducing apparatus into which tape cassette is loaded, and a second write protect mechanism provided at the position which is not in correspondence with the position where write protect mechanism provided at the other tape cassette is provided, wherein the first write protect mechanism is in write protect state at all times. Thus, when there is loaded tape cassette where recording of information signals is carried out by other recording format into recording/reproducing apparatus corresponding to only tape cassette of a specific recording format of tape cassettes different in the recording format, recording of information signals with respect to this tape cassette is inhibited to realize protection of already recorded data.

Tape cassette having first and second write inhibit mechanisms

This invention is directed to a tape cassette in which a tape body is wound across a pair of tape reels rotatably supported by the cassette body. At the cassette body, a location of a first write inhibit mechanism corresponds to the position of a write inhibit mechanism for another tape cassette. A second write inhibit mechanism is provided at the position that is not in correspondence with the position where write inhibit mechanism provided at the other tape cassette is provided. The first write inhibit mechanism is in a write inhibit state at all times. Thus, when there is loaded a tape cassette where recording of information signals is carried out by a different recording format into recording/reproducing apparatus corresponding to only a tape cassette of a specific recording format of tape cassettes different in the recording format, recording of information signals with respect to this tape cassette is inhibited to realize protection of already recorded data. Discrimination techniques are also disclosed.

A tape cartridge includes a front lid rotatably mounted to a casing for closing a tape loading space thereof, a back lid rotatably mounted to the front lid and including a hood for closing a back-lid opening of the casing and a leg for protecting the back of a magnetic tape positioned in the tape lading space of the casing, an inclined face arranged on the upper side of the hood of the back lid to be adjacent to the casing, and a device for controlling a posture of the back lid. In the state of closing the back-lid opening of the casing, the inclined face gradually increases in level difference with respect to the upper side of the casing toward the casing.

In order to enable both reproduction of the azimuth-recorded old format and recording and reproduction of the new format of a different azimuth angle without increasing the number of heads, the number of channels of rotary transformers and the number of changeover switched, attached on a rotary drum are a head Hw1 and a head Hr1 (whose azimuth angle is -.THETA.) which are located in opposite positions apart by 180.degree., and a head Hw2 and a head Hr2 (whose azimuth angle is +.beta.) which are also located in opposite positions apart by 180.degree.. Another head Hr3 (whose azimuth angle is +.THETA.) is attached on the drum 3 in a position apart from the head Hr1 by 90.degree.. Recording of the narrow-track new format and RAW operation are done by the heads Hw1, Hw2, and reproduction of the new format is done by the heads Hr1, Hr2. Reproduction of a signal recorded in the old format is done by the heads Hr1 and Hr3.

A magnetic tape loading device of which the main body portion may be reduced in size and which assures positive contact under pressure of a magnetic tape with a sliding surface of a drum-shaped magnetic head. The loading device includes a driving unit 21, a first transmission unit 22 driven by the driving unit 21, a first magnetic tape actuating unit 25 moved by the first transmission unit 22 for pulling out a magnetic tape 4 placed on a tape supply reel 8 and a second transmission unit 23 driven by the first transmission unit 22. The loading device also includes second magnetic tape actuating units 26, 27 moved by the second transmission unit 23 for pulling out the magnetic tape 4 for abutting the tape thus pulled out against a sliding surface 90 of a drum-shaped magnetic head 18, a third transmission unit 24 driven by the second transmission unit 23 and third magnetic tape actuating units 28, 29 moved by the third transmission unit 24 for pulling out the magnetic tape placed on a tape take-up reel 9.
