  • Publication number: 20150181585
    Abstract: Provided are a data transmission method and device, which relate to the field of communications. The method includes: when data is transmitted between an REC and one or more REs, arranging extended control words of the one or more REs in a plurality of superframes, wherein connotations of the extended control words at a same position in different superframes are different, and sending the plurality of superframes to an opposite end. By arranging extended control words of one or more REs in a plurality of superframes and different connotations of the extended control words at the same position in different superframes, the solution solves the problem that the requirements cannot be satisfied due to the limited number of control words in the protocol, and has the beneficial effect of increasing control words in the protocol.

  • Patent number: 8848315
    Abstract: A method for forming a magnetic write pole with a trapezoidal cross-section is described. The method consists of first forming a magnetic seedlayer on a base followed by depositing a removable material layer on the seedlayer, and then a resist layer on the removable material layer. A trench is then formed in the resist, and the resist is heated to cause the cross -sectional profile of the trench to assume a trapezoidal shape. The resist is then capped with another resist layer and further heated to cause the width of the trapezoidal trench to become narrower. The cap layer and removable material layer at the bottom of the trench are then removed and the trench filled with magnetic material by electroplating. The resist and seedlayer external to the trench are finally removed to form a write pole with a trapezoidal cross-section.
