I suggest you buy Sony RH 1, which can be burned and sold on Taobao. The price is around 2 K. For discs, I suggest you buy Sony's ES series, about 15 yuan each. The rest of the songs and so on are still very simple. You can use a computer to burn through data lines or optical fibers. If you download music in APEx or FLAC format from the Internet, you can burn it on your computer. If it is a genuine CD, you can burn it through optical fiber or use Sony's MD burner.
In short, you should buy MD first. As mentioned above, you can also consider second-hand. I suggest you look at NH 1, which are all Sony's, and the price is around1K.
By the way, there are basically no CDs burned outside now. You must burn them yourself.
I hope it helps you!
