A tape cassette and a tape streamer drive for driving the tape cassette are provided. MAFN data and VMAFN data are defined so as to indicate the maximum frame number of all frames formed in a partition and the maximum frame number of frames in a valid area in the partition, respectively. The MAFN data and the VMAFN data are stored in a MIC disposed in the tape cassette. The size of an available recording area remaining in the partition is calculated from the MAFN data and the VMAFN data. Thus, a powerful technique is achieved for managing the tape cassette used in a data storage application.

A cartridge case 1 for a magnetic tape cartridge comprises a cartridge case 1 consisting of a lower half 2 and an upper half 3. The lower half 2 is provided with retaining ribs 71 each having a retaining slanted surface 71a such that a plate-like cartridge memory 7 is positioned on the retaining slanted surfaces 71a with its one side 7d lowered and is obliquely supported with respect to a bottom plate 28 of the lower half 2. The upper half 3 is provided with supporting members for supporting various non-resilient constituent parts positioned on the lower half 2 and including the cartridge memory 7. The upper half 2 is provided with a stopper rod 77 such that when the upper half 3 is assembled with the lower half 2, the stopper rod 77 reaches a cartridge memory-rising region before the supporting members contact with the non-resilient constituent parts on the lower half 2.

The recording medium cartridge accommodates a recording medium such as a magnetic tape, a optical and/or magnetic disk, or the like in a cartridge body having an upper half and a lower half. A non-contact type memory device storing information, for example, given when producing the cartridge is provided in a reel of at least one of upper and lower flanges of a tape reel or on a surface facing to the tape winding surface of the body in the cartridge accommodating the tape reel wound with the tape, or in a recessed portion formed in at least one of a bottom surface of the lower half and an upper surface of a slider or in the slider in the cartridge having the slider, or in a transparent window of the body. A part of at least one of the upper and lower halves that corresponds to the memory device may be notched. The memory device may be welded together when fitting other members.

In a tape cassette including a magnetic tape having a plurality of partitions in which recording data is written, numbers P1, P2, P3, . . . respectively assigned to the partitions are arranged in an ascending order from the beginning end BOT of the magnetic tape toward an end EOD thereof. When a partition is newly appended, the last partition is divided, and the region behind the dividing part is used as a new partition which is assigned by a number Pn+1 obtained by increasing the maximum number Pn among the partition numbers which existed before the division, so that partitions can be freely appended or deleted.

A microcomputer reads out cassette management information from an integrated-circuit memory on a cassette to give the same to a digital interface formatter. The digital interface formatter outputs the cassette management information by a digital interface format which packages reproduced digital image and audio signals from an error correction circuit and a sub-code and the cassette management information. Upon dubbing recording, a separation circuit extracts the cassette management information from a dubbing input to give the same to the microcomputer. On the basis of the inputted cassette management information, the microcomputer creates cassette management information corresponding to a program to be dubbed to store the same into the integrated-circuit memory. In this manner, upon dubbing, the image and audio information is recorded onto a tape and the cassette management information is automatically recorded onto the integrated-circuit memory. Thus, the user may avoid a complicated information input task.
摘要:
A recording medium device including a cartridge body within which a tape-shaped recording medium on which information signals are recorded is accomodated, wherein a cartridge discrimination opening (hole) indicating the specification of the recording medium device is provided at the bottom surface side of the cartridge body and positioned in the corner of the portion of the back (face) side opposite to the front side of the cartridge body from which the tape shaped recording medium is drawn out. In addition, a recording and/or reproducing apparatus with a detection mechanism for detecting the cartridge discrimination opening (hole) is provided. The cartridge discrimination opening (hole) is provided in the area where it was previously known to provide plural recording medium specification openings (holes) but which are not provided in the cartridge body.

A casette adapter in which an S-casette (first casette) of the professional digital video format is housed and having a shape identical with an different-sized M-casette (second casette) operates without fail under a simple constitution, without accompanying any fear of damage on a tape. The casette adapter capable of housing an S-casette (2) comprises an adapter (1) whose shape is identical to an different-sized M-casette. Reels (5, 6) and a reel brake releasing member (7) of the S-casette (2) are exposed while the S-casette is mounted in the casette adapter. The adaptor (1) includes a rear door (12) capable of opening and closing. The rear door (12) comprises contacts (14) for reading identification signal by contacting the identification terminal of S-casette, wirings (16) for coupling the contacts (14) with an identification terminal (15) provided in a same location as that of M-casette and a lever (18) for opening/closing an anti-erasing window in linkage with the anti-erasing gear of S-casette (2).
