Title: Artur Lang: Innovator in Magnetic Disk Technology
Introduction
Artur Lang is a notable inventor based in Worms, Germany. He has made significant contributions to the field of magnetic disk technology, holding 2 patents that showcase his innovative approaches.
Latest Patents
One of his latest patents is the "Pulsed DC sputtering method of thin film magnetic disks." This invention describes a method and apparatus for depositing an underlayer and/or a magnetic thin film layer on a data storage disk. The sputtering power is supplied in the form of pulses during the application of the underlayer and/or magnetic storage to periodically ignite the plasma and increase the charge-carrier density in the sputtering chamber. The repetition frequency and parameters for the pulses and pauses between pulses are adjusted to achieve a desired nominal value for the coercive field strength of the magnetic layer. Preferably, the repetition frequency of the power switching is from 10 to 80 kHz, and the ratio of pulse length to pulse pause is within 5:1 to 1:5.
Another significant patent is the "System for testing magnetic head/disk interfaces." This method measures the properties of a slider/disk interface in a magnetic disk storage apparatus by measuring a triboelectric current flowing between the disk and slider. The rotational speed is adjusted between 100 and 500 rpm to obtain a frictional contact between the disk and slider. The shape of the tribo current curve obtained during the measuring time interval is analyzed. An early maximum of the tribo current amplitude and a subsequent continual decay indicates a good slider/disk interface and a long lifetime.
