A multi-band antenna and a notebook computer with a built-in multi-band antenna are disclosed. Since the multi-band antenna is installed at the inner side of a upper and a lower case, it is much favored for a radio communication when a computer is in use by standing up a display device. The multi-band antenna includes at least two transmitting and receiving parts formed with different lengths to fit frequency bands, so that a remote communication of at least two or more bands can be made. The multi-band antenna is positioned between liquid crystal and a side wall of the lower case, and a grounding unit is installed to contact a liquid crystal frame. That is, since the grounding unit is grounded to the liquid crystal frame and the bracket, substantially, the liquid crystal frame and the bracket are wholly grounded to ensure a stable radio frequency communication.

A capstan motor used in a magnetic recording and reproducing apparatus includes a rotatable rotor section provided with a capstan shaft, a stator section rotatably supporting the capstan shaft opposite to the rotor section, and a guide section formed at one side of the stator section for guiding the movement of a tape draw-out section for leading a tape to wind around the outer circumference of a head drum. Here, the structure of the a bearing holder and a base plate of the stator section has several functions simultaneously for decreasing the product size and the number of elements to contribute to miniaturization of a deck and enhance productivity of manufacturing the product.
