Abstract: The present invention discloses a power control method and apparatus. The power control method of the present invention includes: when a service runs in a first-standard communication system, determining a transmit power P1 of the first-standard communication system; determining that the transmit power P1 is higher than or equal to a threshold value P2 of power interference of the first-standard communication system to a second-standard communication system; use a power lower than P1 to send data on an interference frequency of the first-standard communication system. According to the power control method in the present invention, a signal transmit power of the interfering frequency of the first-standard communication system can be reduced when it is determined that the first-standard communication system will cause interference to the second-standard communication system, thereby reducing the interference of the first-standard communication system to the second-standard communication system.

Abstract: A storage unit includes a U-shaped magnetic track, a first drive circuit, a second drive circuit, a first drive port, and a second drive port. The U-shaped magnetic track includes a first port, a second port, a first storage area, and a second storage area. By controlling input voltages of the first port, the second port, the first drive port, and the second drive port and driving the first drive circuit, a current pulse is generated in the first storage area, and a magnetic domain wall in the first storage area is driven to move. By controlling the input voltages of the first port, the second port, the first drive port, and the second drive port and driving the second drive circuit, a current pulse is generated in the second storage area, and a magnetic domain in the second storage area is driven to move.

Abstract: An information storage apparatus includes a magnetic track, a writer, and a reader, where the magnetic track includes a number of magnetic domains. Each magnetic domain is divided into at least two magnetic regions, and the writer is disposed on the magnetic track, and configured to write information to the at least two magnetic regions of each magnetic domain. The reader, disposed on the magnetic track, is configured to read the written information from the at least two magnetic regions. Therefore, multiple pieces of valid information are written to one magnetic domain of the magnetic track, thereby increasing storage density of the magnetic track, and expanding a storage capacity of the storage apparatus.
