Title: Process and apparatus for a combined wobble-track servo arrangement
Inventor: TSUYOSHI TOSHIAKI
IPC: G11B7/09
Filed: 1986-12-05
Abstract: A combined wobble-tracking servo arrangement uses a rotatable optical disc, which has a head label field and a data field arranged alternately along the direction of rotation, and which contains preliminary grooves which are formed in at least the data field and at least one pair of wobbled track markers applied in each of the head label fields in a wobbled relationship relative to the track centre. A light spot is directed in the direction of and onto the optical disc in order to sense a push-pull track error signal from the reflection of the light spot which is diffracted by the preliminary groove, and a wobbled track error signal is sensed by the reflection of the light spot which passes through the wobbled track markers. After attenuation of the amplification of the wobbled track error signal by a low-pass filter, so that the amplification of the wobbled track error signal is equal to the amplification of the push-pull track error signal at a frequency fe which satisfies the following relationship:  1/50.N.fd<fe<1/5.N.fd where N is the number of head label fields comprised in one full revolution of the disc, and fd is the rotational frequency of the disc, the attenuated wobbled track error signal is combined with the push-pull track error signal in order to produce a combined track error signal, which is used for track control.

Title: Process for producing layers having very hard diamond-like and/or low-friction properties
Inventor: REPENNING DETLEV DIPL CHEM DR
IPC: C30B23/02
Filed: 1987-04-10
Abstract: A process is proposed for producing layers having very hard diamond-like and/or low-friction properties. In this process, a target material (13) is converted into a target material plasma in a vacuum (11) by means of an electric arc (20). The target material (13) is at a particular electric potential. A substrate (14) which lies at a lower electric potential than the target material (13) is the goal of the atomic charged target material. The atomic target material reaches the substrate (14). According to the invention, it is proposed that the electric arc (20) acts directly on the target material (13) to generate the target material plasma, and that the target material (13) is thus converted directly into the vapour phase, the target material being carbon. <IMAGE>
