Title: Magnetic disc lubricant layer structure and manufacturing method of the same
Inventor: YANG PEI-SHIANG
IPC: G11B7/24
Filed: 1998-01-16
Granted: 2000-11-21
Abstract: This invention is about the magnetic disc lubricant layer structure and manufacturing method of the same. The main purpose of this invention is to solve the flying stiction problem generated as the hard disc head flying lower and lower. The cause of generating this flying stiction is due to the fact that when the magnetic head is flying at a low altitude above the data zone of the magnetic disc for a period of time, the free/mobile lubricant of the data zone can be adsorbed. Part of the free/mobile lubricant is then brought back as the magnetic head flies back to the landing zone such that the magnetic head can not take off in the next flight because the stiction is too heavy. The inventor designs a magnetic disc lubricant layer structure and the manufacturing method of the same to reduce the amount of free/mobile lubricant on the data zone and maintain that on the landing zone in an appropriate value. Therefore, the magnetic head has enough lubrication for both takeoff and landing such that there is no flying stiction generated and the purpose stated above is obtained.

The refractive surface refracts an incident light beam, the second reflection surface reflects a light beam refracted by the refractive surface toward the first reflection surface, and the first reflection surface focuses a laser light beam reflected from the second reflection surface on the beam focusing surface as a focused beam spot. The optical focusing system can be used in an optical pickup. The optical pickup uses the optical focusing system to generate, from a light beam e.g. laser light emitted from a light source, a beam spot used for recording or reading information to a recording medium. The optical pickup uses a near field effect provided by an optical focusing system according to the present invention, to allow a superior density of recording or reading. Further, the optical focusing system according to the invention can use a light beam having a beam diameter smaller than that of the laser beam used for an existing optical focusing system for forming a near field. Thus, the optical pickup according to the invention can record or read information on an optical disk having a surface recording density of 10 Gbit/inch<2> or mare. Even if an incident light beam inclination occurs due to movement of the disk or the optical pickup, information can be recorded on or read from a disk accurately. Also, the assembly of the optical focusing system and the adjustment of the assembled optical focusing system are easily performed.

In accordance with the field strength of the reception signals, a low noise amplifying section bypasses the reception signals without an amplification at the strong field strength, while the low noise amplifying section amplifies the reception signals at the weak field strength. Further, the transceiver operates with the maximum gain at the weak field strength, and the gain is lowered at the strong field strength. Therefore, the power consumption can be lowered, thereby extending the life expectancy of the dry cell battery.

Title: Method for the prevention of unauthorized duplication of information-carrying substrates
Inventor: WAINERDI THOMAS J
IPC: G11B19/00
Filed: 1999-09-04
Granted: 2001-09-11
Abstract: The present invention relies on one or more intrinsic physical or chemical characteristics of the substrate materials to distinguish unauthorized duplications of information-carrying substrates. In one aspect of the present invention, a method is disclosed for preventing unauthorized duplication of information to be distributed on information-carrying substrates, by requiring such distribution to be through a substrate of a type selected from a designated class of substrates. Unauthorized duplication can be identified by relying on at least one designated intrinsic physical or chemical characteristic that distinctively represents the type of substrate. The designated intrinsic characteristic is detected by an information processing device that is configured to operate to access the information authorized to be distributed using the type of substrate when the designated characteristic has been detected. Accordingly, any duplication of the information on other types of substrates outside said class of substrates would be recognized as not being an authorized duplication by said information processing device. By controlling the availability of the information-carrying substrate material to only authorized information-carrying substrate producers for production of the information-carrying substrate, unauthorized duplication of information-carrying substrates by unauthorized production entities can be prevented. In a further aspect of the present invention, a process is disclosed for the prevention of unauthorized duplication of information-carrying substrates. The process comprises monitoring the ""order to delivery"" process such that information-carrying substrates are produced without allowing substrate material and/or substrates to be obtained by an unauthorized party.

Filed: 1999-11-16
Granted: 2001-04-11
Abstract: The object of the present invention is to provide a manufacturing for self-aligned unlanded via in semiconductor metal interconnects. The method uses simple processes without new material, and because of the formation of self-aligned dielectric structure, it is able to increase the process window between the mask production and the dielectric etching and avoid a short circuit or bridging between metal wires due to the etching between the upper and lower metal layers and left and right metal layers caused by dielectric etching between metal wires, and prevent the leakage current of transistor under threshold voltage from reduction of yield or reliability, which results in damaged wafers. Furthermore, because of the formation of unlanded dielectric structure, it can reduce the occupied chip area by the dielectric alignment to increase the device density and chip integrity.
