Product developed based on creating a Walkman roughly the size of a cassette case. This model featured one AA battery, head, pinch roller, and headphone jack arranged in a row, with the cassette placed horizontally alongside this structure. From this point forward, the Walkman was established as a modern necessity, easily carried in a handbag or pocket.
