Call it Walkman.

Walkman refers to a portable pocket player, which is a category of electronic products. The term originally came from a brand of Japan's Sony Corporation (Sony), and the Chinese name was changed from "Walkman".

In addition, "Walkman" is the general name for a personal portable music player produced by Sony Corporation of Japan. With the popularity of walkman, walkman has become a cultural phenomenon. In 1979, the world's first personal portable tape player was born at Sony. Its model was TPS-L2, and the product name was Walkman.

Extended information:

Discs that can be used with the Walkman:

One is a recordable magneto-optical disc for home recording.

The other is a non-recordable disc for music distribution (there is actually an uncommon hybrid mode).

Both formats of discs are 64mm in size and use an audio compression technology called ATRAC and a specific storage format. It is precisely because of the existence of this audio compression technology that Convenient MD can store about 60 to 80 minutes of compressed 44.1Khz, stereo music. There are many reasons why MD is so popular, the most important of which is that it is much smaller than Discman.

The MD rewritable magneto-optical disk itself is only 64 mm in diameter and 1.2 mm thick. It is built into a 72×68×5 mm hard plastic protective sleeve and looks like a computer. The structure of the three-inch pan is similar, but the actual size is smaller than the three-inch pan. With a carrier that is much smaller than a CD, you can enjoy sound quality similar to that of a CD.
