A single step portion 54 is formed along the length direction.

The front ends of both side plates 51 and 52 have rectangular notches,
An upper protruding piece 55 and a lower protruding piece 56 are formed.

Note that the reference numeral 63 in Figure 1 is a herad core.

Further, as shown in FIG. 5, the thickness dimension 9 of the adapter body 48 is formed to be approximately the same as the width dimension Ml of the opening 60 of the opening fi 46, and the length dimension 2B of the adapter body 4B is , the length dimension JL+o of the opening 60 is formed substantially the same, and the width dimension 6 of the adapter main body 48 is formed substantially the same as the depth dimension appearance of the recording adapter mounting section 46.

Next, the compact cassette 35 with the recording adapter 34 attached is loaded into the playback machine and the playback machine is operated in the playback state, while the main switch of the controller 24 is turned from the OFF state to the REC state, and the function switch is turned on. 30 at the MIC8L position. As a result, the hubs 8a and 8b begin to rotate, and the magnetic tape 5 wound around one hub 8a travels toward the other hub 8b, where it is recorded by the recording head 49. Further, in this case, since the reproducing machine is in the reproducing state, the reproducing head 65 moves forward into the magnetic head entry recess 66 and comes into pressure contact with the magnetic tape 5 as the reproducing head 65 operates. Since the magnetic tape 5 that is in sliding contact with the reproducing disc 65 has already been recorded by the recording disc 49, the recorded contents of the magnetic tape 5 are reproduced by the reproducing disc 65. Therefore, the operator can monitor the recorded content by keeping the playback device in the playback state.

Further, when the recording on one running surface of the magnetic tape 5 is completed, if the playback device is equipped with an auto-reverse function, as in the case of the above embodiment, the recording adapter 34 is connected to the compact cassette. The compact cassette 35 is taken out from the recess 46 of the magnetic tape 35, reversed, inserted into the fourth part 46, and fixed, and the compact cassette 35 is loaded into the playback machine as it is with the head core 63 of the recording head 49 in contact with the other running surface of the magnetic tape 5. By doing so, it is possible to record the other running surface. If the player is not equipped with an auto-reverse function, take out the compact cassette 35 with the magnetic tape 5 wound onto the winding hub 8b from the player, and insert the #1 sound adapter 34 from the recess 46. After pulling it out and inverting it, it is inserted and fixed into the recess 46. Then, by inverting the compact case 2 card 35, loading it into the playback machine, and operating it, it is possible to record the other side.

In addition, in each of the embodiments described in Section 2, the case where the connection part provided on the half of the cassette tape consists of four parts is explained as an example, but this is not limited to each of the embodiments. In addition, it is sufficient that the recording head is configured so that it can come into contact with the magnetic tape when the adapter main body is attached.

Recording adapter 11.34 applied to each of the above embodiments
are connected to the controller 24 and harness 58, and the playback device is equipped with a recording adapter 11.3.
All you have to do is load the compact cassette 1 with 4 attached.
The controller 24 is configured separately from the player. Therefore, unlike portable cassette players that have a recording function that have been commonly used in the past, all components necessary for recording, such as microphones, switches, and circuits, are formed separately from the playback device. Therefore, it does not increase the weight or size of the playback device itself, and it only needs to be used when recording is necessary, which reduces the ease of handling and portability of the portable cassette player itself. Never.

Also, in general, for recording heads.

In order to reduce high-frequency loss, the impedance of the coil is several tens of ohms, and for playback-only heads, the impedance of the coil is IKΩ to obtain a large playback output.
On the other hand, the impedance of the head for both Qft and M raw is around 700Ω, considering the playback output.

In the recording-only head, the front gap is 5-tog in consideration of the recording demagnetization effect, and the rear gap is formed into an A body to prevent magnetization. In some cases, the front gap is 1.5p to 3 to reduce gap loss. On the other hand, in the recording/reproducing head, the front gap is formed narrower than in the Q acoustic head.

Therefore, in portable cassette players that cannot record and playback, recording and playback are performed using the same magnetic head, so it is difficult to set the optimal impedance and gap for each recording or playback. However, when recording or playing back using a Q-sound playback head, the dynamic range and S/N will be lower than when recording using a recording-only head or when playing back using a playback-only head. There was a problem that the musical characteristics were inferior in comparison.

However, when the cassette tape according to each of the above embodiments is used with a recording adapter, the recording head provided on the recording adapter performs recording, and the cassette tape equipped with a playback-only cassette player also performs recording. Playback can be performed by a playback head, and recording and playback can be performed using separate heads.

As a result, unlike the case where recording and playback are performed using the same magnetic head, recording or playback can be performed using a magnetic head that has the optimal impedance and gap for each recording or playback, which improves the dynamic range. Music characteristics such as S/N ratio can be improved.

[Effects of the Invention] When the cassette tape according to the present invention is used, even if it is a playback-only cassette player without a recording function, a recording adapter can be attached to the connection part provided on the half of the cassette tape. By loading the magnetic tape into a cassette player, operating it in the playback mode, and supplying power to the recording head, it becomes possible to record onto a magnetic tape.

Furthermore, in the cassette tape according to the present invention, since the recording adapter is used by being attached to the cassette tape, there is no need to increase the weight of the cassette player itself.

Furthermore, since the size of the cassette player itself is not increased, the portability of the portable cassette player is not impaired.
