Company is China's optical disc industry is currently one of the most strength and development potential of the company, set product design, research and development, production, sales as one. After many years of healthy and steady development, with the world's advanced technology can record the disc production line 42 (108 head), the company's products by domestic and foreign customers of all ages and praise, in particular, self brand has grown into China's optical disc industry leader brand. Magnetoelectric sensor has two basic components: A is constant DC magnetic field of the magnetic circuit system, in order to decrease sensor volume. In general, the permanent magnet; another is coil, by it and magnetic flux linkage produces induced electromotive force. The induced electromotive force is proportional to the magnetic flux change rate or the relative velocity between the coil and the magnetic field, so there must be a relative movement between them. As a moving part, it can be a coil, or a permanent magnet. Therefore, it is necessary to choose the structure form, material and structure size of the sensor to meet the basic performance requirements of the sensor.

For inertial sensors, the specific calculation is based on the use of occasions, the use of objects to determine the structure of the form and size of the small (that is, contour size), and then according to the structure of the initial determination of magnetic circuit system, magnetic circuit in order to determine the magnetic induction intensity B. So, the sensitivity of technical indicators for a given value of S and determine the B value, the number of turns of the coil N by S = e/v= B L N can. Because in the magnetic circuit system is determined, the size of the air gap have been identified, the size of the coil have been identified, namely, iota have been identified. According to these parameters, the diameter of the coil can be determined by D. From the angle of improving the sensitivity, the B value is large, the S value is also big, therefore the magnetic circuit structure size should be bigger. As long as the size of the structure allows, the magnet can be as large as possible, and select the B value of the permanent magnet material, N can also get a large number of turns. Of course, the increase of the wire is also subject to other conditions, the selection of the parameters to be considered, as far as possible. Companies always adhere to the "people-oriented, scientific and technological innovation, quality first, customer first" management philosophy and quality policy, as the human resources for the industrial development of the source; as the product quality for the enterprise life; as scientific research and development as the driving force. Using modern information technology, advanced management concepts and methods are introduced into the management process, improve the management efficiency and level, and promote the management of innovation, has been fully established "ISO9001" international quality management system, the company's management and management activities have achieved the management system, system standardization. In the face of consumer groups on the demand for large capacity of the disc, the company plans to introduce Blu ray disc production line, hoping to participate in the company's future development, and become a high definition optical storage industry standard manufacturers, continue to lead the Chinese optical disc industry forward. The future development of the enterprise is to start the international brand, the international market, and then become the Asia Pacific optical disc base.
