DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a recording medium cartridge in which a tape-shaped recording medium and a disk-shaped recording medium (disk) are stored in the same housing, and a recording medium driving device.

[0002]

2. Description of the Related Art As a recording / reproducing apparatus having a configuration capable of recording / reproducing an information signal to be recorded / reproduced using a tape-shaped recording medium, a magnetic tape is used. Tape recorder capable of recording / reproducing data, video tape recorder (VTR) capable of recording / reproducing a video signal (or a video signal and an audio signal accompanying the video signal), data for a computer For example, a streamer or the like for storing the information has been practically used. The magnetic tape is housed in a container having a special structure in order to facilitate the operation of attaching and detaching the magnetic tape to and from the magnetic recording / reproducing apparatus such as the tape recorder, VTR, and streamer, and to ensure the protection of the magnetic tape. It has been widely practiced to use cartridge tapes and cassette tapes in such a state.

As a video cassette recorder (VCR) configured to perform a recording / reproducing operation using a cassette tape as described above, for example, a VHS (registered trademark) system widely known worldwide. In addition to the VCR configured according to the standard of the so-called 8 mm video system, there are a VCR configured according to the standard of the so-called DVC system, and the like. The above-mentioned VCR rotates a rotating drum provided with a pair of rotating magnetic heads having opposite azimuth angles at 180-degree symmetrical positions at a predetermined number of rotations, and rotates the rotating surface of the drum. The magnetic tape running at a predetermined running speed in a state where the position of the reference edge of the magnetic tape obliquely wound on at least a part of the magnetic tape is regulated by the guide portion provided on the drum is rotated by the pair of rotating magnetic tapes. When helical scans are sequentially and alternately performed by the heads, 18
The helical scan type magnetic recording / reproducing apparatus is configured so that sequential recording traces can be sequentially formed adjacent to the magnetic tape in correspondence with the rotation every 0 degree.

[0004] Tape cassettes each having a specific configuration in accordance with the individual standards for each of the above-described methods have a predetermined length used for recording and reproducing information signals to be recorded and reproduced. A reel for incorporating at least two reels on which a magnetic tape is to be wound and a reel lock mechanism for locking the reel when not in use, and for releasing the locked state of the reel by the reel lock mechanism And a tape cassette housing having a bottom provided with a reel lock release hole into which the lock release member is to be inserted.

By the way, the most common recording format of a recorded magnetic tape on which a plurality of programs are recorded in series on a time axis by a magnetic recording / reproducing apparatus is a recording area for each program in a plurality of programs. They are arranged in series in the longitudinal direction of the tape. Therefore, in the conventional magnetic recording / reproducing apparatus, when a specific program is selected and reproduced from the recorded magnetic tape T on which a plurality of programs are recorded, the first part of the specific program is recorded. In order to perform reproduction from the portion where the magnetic tape is located, it is necessary to fast forward or rewind the magnetic tape at a high speed to perform cueing. Therefore, it is difficult to select a specific program from a plurality of programs in a short time. Naturally, it has not been possible to confirm the contents of the plurality of programs in a short time. Is widely known as a problem when recording and reproducing information signals using a magnetic tape.

As means for solving the above problems, a recording / reproducing apparatus capable of quickly reading out specific information from recorded information, for example, recording / reproducing of various discs having a recording / reproducing function. The apparatus is used as an auxiliary recording / reproducing apparatus, and only the head of each program in a plurality of programs to be reproduced by a magnetic recording / reproducing apparatus (VCR) used as a main recording / reproducing apparatus is used as the auxiliary recording / reproducing apparatus. V is used as a main recording / reproducing apparatus, which reproduces in advance by a recording / reproducing apparatus and reproduces a part following a head part of a program.
In the case where the CR takes over, the switching between the reproduction output from the auxiliary recording / reproducing apparatus and the reproduction output from the VCR is performed using the address information recorded on the magnetic tape. As a result, Japanese Patent Laid-Open No. 4-16079 discloses a solution for enabling selective reproduction of a specific program in a short time.
It is disclosed in JP-A-7-123346 and the like.

However, in the above-mentioned solution, V
The CR magnetic tape and the semiconductor memory are used in combination. However, since only a small memory capacity can be used as the semiconductor memory attached to the tape cassette housing, there is a problem that the head portion of many numbers cannot be stored. Further, since the VCR magnetic tape and the semiconductor memory are used in combination as described above, the operating power for operating the semiconductor memory installed in the tape cassette housing is reduced.
The power must be supplied from a battery or the main unit of the recording / reproducing apparatus, and it is necessary to provide a connector for supplying power for operation to the semiconductor memory in the tape cassette housing. become. In the above-mentioned solution, a recording / reproducing apparatus is configured by using a storage device using a disk medium in addition to using a magnetic tape of a VCR in combination with a semiconductor memory.

[0008]

However, the above-mentioned conventional recording / reproducing apparatus constructed as an integrated recording / reproducing apparatus by combining a storage device using a disk medium and a magnetic recording / reproducing device using a magnetic tape. However, there is a problem that the configuration is complicated, the size is large, and the price is high. Therefore, the appearance of a recording / reproducing apparatus which can solve the above problems has been expected.

FIG. 11B shows an optical disk Od (Od1, Od1).
The recording mode of the information recorded in 2) is shown. At the beginning of the recording area of the optical disc Od (Od1, Od2),
As illustrated in FIG. 11B, the management data [for example, the management data of the entire tape, the start address of the recording area for each program information on the magnetic tape T or the optical disc Od (Od1, Od2), and the program information Title, recording date and time, etc.].

The management data recorded at the head of the optical disc Od (Od1, Od2) is read and used each time one of a plurality of pieces of program information recorded on the magnetic tape is reproduced. However, at the start of the operation of the recording / reproducing apparatus, the management data recorded on the optical disc Od is reproduced and stored in the memory of the control unit and the signal processing unit 72 in the recording / reproducing apparatus. When the recording / reproducing apparatus operates, the search time can be reduced by using the management data.

In the example of FIG. 11, assuming that the magnetic tape T has a tape length that allows continuous recording for 6 hours (360 minutes), the magnetic tape T sequentially stores one-hour program information. Only six programs can be recorded. Assuming that the recording / reproducing apparatus is capable of fast-forwarding (rewinding) at 120 times speed, the entire magnetic tape T can be rewound in about 3 minutes. Therefore, as exemplified in FIG. 11B, information for three minutes at the start of each of the six pieces of program information to be recorded on the magnetic tape T is written on the optical disc Od.

d1, Od2). For example, even if the information of the recording time of 20 minutes including the recording time of the management data of 2 minutes is recorded on the optical disc Od (Od1, Od2) of the recording time, the optical disc Od Information in any part of the recording area of (Od1, Od2) can be accessed in a short time.

That is, in the case of only the magnetic tape T on which recording was performed for 360 minutes as in the above-described example, the running speed of the magnetic tape was fast forward (rewinding) at 120 times speed.
Even if this is possible, it is necessary to anticipate that an access time to any program information recorded on the magnetic tape T will require about 3 minutes or more. However, in the present invention, as described above, for each start portion of each program information, for example, the program information for three minutes corresponding to the entire rewind time of the magnetic tape T is managed on the optical disc Od (Od1, Od2). If the program information is to be recorded successively following the data recording area and the reproduction of any program information is desired, the program information is first reproduced from the optical disc Od (Od1, Od2) for 3 minutes, and the program information is reproduced. During three minutes, program information desired to be reproduced on the magnetic tape T is searched, and the program information reproduced from the optical disc Od (Od1, Od2) is set in a standby state for starting the reproduction operation for the program information desired to be reproduced. After the start of the information, the program information reproduced from the magnetic tape T is smoothly switched and reproduced, so that the program information can be changed to any program information. The access time can be made short access time of the optical disc Od (Od1, Od2).
