Filed: 1984-08-31
Abstract: PURPOSE:To decide the state of the relative positional precision of the first and second alignment marks, which is beyond the allowable error X, in two stages and to enable to improve the workability for pattern alignment by a method wherein the first alignment mark, which is deleted its four rectangular top parts in a rectangle respectively and is formed into a cross shape, is combined with the second alignment mark, which is formed into a rectangular frame form in such a size that the second alignment mark encircles the outer periphery of the first alignment mark, in such a way that the first alignment mark is made to position on the center of the second alignment mark. CONSTITUTION:A first alignment mark 10 is deleted its four rectangular top parts in a rectangle respectively and is formed into a cross shape. A second alignment mark 20 is formed into a rectangular frame from in such a size that the mark 20 can encircle the outer periphery of the first alignment mark 10. A size (c) is set in such a way as to correspond to an error Y that one half of a difference between a size (b) and the size (c) is beyond the conventional allowable error X. When the relative positional precision of the patterns of the two marks is within the allowable error X and is the best, both marks 10 and 20 are transferred on the wafer in such a way that the first alignment mark 10 is made to position on the center of the second alignment mark 20. Then, in case the positional precision is beyond the allowable error X, the precision is decided to be one not beyond the error Y when the region shown by (d) is leaving between the first and second alignment marks 10 and 20, and when the region is not leaving, the positional recision is decided to be one beyond the error Y.

Title: Servo information writing system
Inventor: OOTA YUJI
IPC: G11B21/10
Filed: 1986-08-08
Abstract: PURPOSE:To substantially dissolve a defect even if the defect due to a defect of a face plate exists in servo information written on a disk type recording medium, by modulating the write time width of servo information to be written on the detected defective position and writing it again. CONSTITUTION:If the read waveform amplification level in a certain position on the disk type recording medium where servo information is written with a time width Tc is not satisfactory because of the presence of defects of the face plate in accordance with the characteristic of waveform amplification level V of read servo information corresponding to write time width T of servo information, the time width is modulated to Tc+DELTAT only in this position to rewrite servo information. Thus, the read waveform amplitude level in this position is increased to reach a reference level Vp regardless of existence of the defect of the face plate. If the read waveform amplitude level is excessive, the time width is modulated to Tc-DELTAT to rewrite servo information. Thus, the read waveform amplitude level coincides with the reference level similarly.
