If the player is not equipped with an auto-reverse function, the compact cassette 35 with the magnetic tape 5 wound around the first winding hub 8b is removed from the player.

The recording adapter 34 is pulled out from the recess 46, turned over, and then inserted and fixed into the recess fi4B. Then, by inverting the compact cassette 35, loading it into the playback machine, and operating it, the other side can be recorded.

In addition, in each of the above embodiments, the case where the connection part provided in the half of the cassette tape consists of a recess was explained as an example, but the embodiments are not limited to the above embodiments, and the adapter main body can be attached, It is only necessary that the recording head be configured so that it can come into contact with the magnetic tape when the adapter body is attached.

The recording adapters 11.34 according to each of the above embodiments are all connected to the controller 24 by a harness 58, and it is only necessary to load the compact cassette 1 with the recording adapters 11.34 attached to the playback machine. 24 is configured separately from the playback machine.

Therefore, unlike portable cassette players with recording functions that have been commonly used,
All parts necessary for sound, such as microphones, switches, and circuits, are formed separately from the playback device, so there is no increase in the weight or size of the playback device itself, and there is no need for recording. Since it only needs to be used in certain cases, the ease of handling and portability of the portable cassette player itself is not impaired in any way.

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, in the case of a head that also serves as a playback, the impedance is around 700Ω, considering the playback output.

In the recording-only head, the front gap is 5 to lOμ in consideration of the recording demagnetization effect, and the rear gap is for preventing magnetization.

In the read-only head, the front gap is 1.5 mm to 3 mm in order to reduce gap loss. On the other hand, in a recording/playback head, the front gap is formed narrower than in a recording-only head.

Therefore, in portable cassette players capable of recording and playback, since recording and playback are performed using the same magnetic head, it is difficult to set the optimal impedance and gap for each recording or playback. When recording or playing back using a recording/playback head, the dynamic range, S/N ratio, etc. There was a problem that the musical characteristics were inferior.

However, when the recording adapter according to each of the above embodiments is used, recording is performed using the recording head installed on the recording adapter, and playback is performed using the playback head installed on the playback-only cassette player. You can do it! Sound 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 f-yap for each case of recording or playback, so the dynamic range and Music characteristics such as S/N ratio can be improved.

[Effect of the invention] When the recording adapter according to the present invention is used, even if it is a playback-only cassette player without a recording function,
By attaching a recording adapter to the connection part on the half of a cassette tape, loading it into a cassette player, operating it in playback mode, and inputting power to the recording head, it becomes possible to record on a 1m magnetic tape. .

In addition, since the recording adapter according to the present invention is attached to a cassette tape, it does not increase the weight or size of the cassette player itself.
The original portability of a portable cassette player is not compromised.
