Abstract: The present specification discloses a method for detecting an aneuploid of a Brassica oleracea plant, including: performing real-time PCR using DNA extracted from a sample derived from a Brassica oleracea plant to be tested as a template and DNA markers specific to each of two or more chromosomes of Brassica oleracea plant; and detecting chromosomal aneuploidy from a relative difference in amplification amount between the obtained DNA markers. According to one embodiment of the present invention, it is possible to simply, accurately, and rapidly detect an off-type (chromosomal aneuploid) that may occur in Brassica oleracea varieties, in a laboratory equipped with a general molecular biological equipment in the course of seed quality control and breeding research.

Abstract: A tape cassette including a cartridge and one tape reel provided in the cartridge, with a recording medium in the form of a tape being wound upon the tape reel. In the tape cassette, a leader tape that is more rigid than the recording medium in the form of a tape is connected to an unwinding end of the recording medium in the form of a tape; a toothed portion (a protrusion) is formed on at least a portion of both side edges of the leader tape; the tape reel has a flange on a top portion and on a bottom portion of a hub, and feed teeth (engaging portions) that engage the protrusions of the leader tape are formed on outer peripheral edges of the flanges. Rotation of the tape reel in one direction causes the engaging portions to feed the protrusions, whereby the leader tape is sent out from the cartridge. The tape cartridge of the invention can be reliably mounted to a recording/reproducing apparatus.

Abstract: A tape cartridge housing a magnetic tape includes an auxiliary storage medium having a storage unit in which to store the recording medium information such as design parameters or the number of times of recording and/or reproduction of the magnetic tape, and a transmission/reception unit for effecting inputting/outputting of the recording medium information with the recording and/or reproducing apparatus. The auxiliary storage medium is mounted so that the transmission/reception unit is exposed to the outside through an opening provided in a lateral surface of the main cartridge body unit not obstructing the loading of the magnetic tape, that is in a surface of the main cartridge body unit other than its front surface as an inserting end of the tape cartridge into the inside of the recording and/or reproducing apparatus.

Abstract: A tape driving apparatus which operates corresponding to the individual tape cassette loaded therein. A tape driving unit is included for running a magnetic tape included in the tape cassette and for recording/reproducing information to/from the magnetic tape. A memory driving unit is provided for reading/writing management information from/to a memory by implementing a predetermined communicating process. The memory is located at the tape cassette and stores the management information for managing a recording/reproducing operation to/from the magnetic tape. Identification information of the tape cassette is detected from the memory. A knowledge information memory stores knowledge information formed of operation specifying information and conditional information corresponding to the identification information of the tape cassette. The conditional information is evaluated based on the identification information.

Abstract: A tape cassette including a cartridge and one tape reel provided in the cartridge, with a recording medium in the form of a tape being wound upon the tape reel. In the tape cassette, a leader_tape that is more rigid than the recording medium in the form of a tape is connected to an unwinding end of the recording medium in the form of a tape; a toothed portion (a protrusion) is formed on at least a portion of both side edges of the leader_tape; the tape reel has a flange on a top portion and on a bottom portion of a hub, and feed teeth (engaging portions) that engage the protrusions of the leader tape are formed on outer peripheral edges of the flanges. Rotation of the tape reel in one direction causes the engaging portions to feed the protrusions, whereby the leader_tape is sent out from the cartridge. The tape cartridge can be reliably mounted to a recording/reproducing apparatus.

Abstract: 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.

Abstract: A recording/reproducing apparatus is provided in which an increase in recording density is achieved and in which the tape loading mechanism is simplified. A recording/reproducing apparatus of the type which uses a tape cassette which has a tape reel in a cartridge and in which a tape including a tape-shaped recording medium is wound around the tape reel, includes a take-up reel adapted to take up the tape-shaped recording medium and having a height equal to that of the tape reel of the tape cassette attached to the recording/reproducing apparatus, and a rotary head for recording and/or reproducing information on and/or from the tape-shaped recording medium by a helical scan system.

Abstract: A tape cassette including a cartridge and one tape reel provided in the cartridge, with a recording medium in the form of a tape being wound upon the tape reel. In the tape cassette, a reader tape that is more rigid than the recording medium in the form of a tape is connected to an unwinding end of the recording medium in the form of a tape; a toothed portion (a protrusion) is formed on at least a portion of both side edges of the reader tape; the tape reel has a flange on a top portion and on a bottom portion of a hub, and feed teeth (engaging portions) that engage the protrusions of the reader tape are formed on outer peripheral edges of the flanges. Rotation of the tape reel in one direction causes the engaging portions to feed the protrusions, whereby the reader tape is sent out from the cartridge. The tape cartridge of the invention can be reliably mounted to a recording/reproducing apparatus.
