摘要： A method is provided for the formation of high precision metal slugs by cold forming. A metal column starting material is subjected to a preforming step in which the starting material is cold forged with a pair of upper and lower metal dies provided with concave recesses to produce a primary product having a barrel shape having a high degree of parallelism on the ends. The resultant primary product is subjected to an upsetting step in which the barrel shape is crushed while maintaining parallelism to obtain a secondary product. The resultant secondary product is then subjected to an ironing step in which the outer diameter of the secondary product is reduced to obtain a high precision slug having an outer diameter which is substantially the same as the outer diameter of the desired final product for which the slug will be utilized.

摘要： A recording method for an optical disc drive and an optical disc drive capable of preventing a light source of a laser beam or a laser driving portion from becoming uncontrollable as they are heated to high temperatures above their compensation temperatures, and thereby enabling recording to be continued in a stable manner without being interrupted or stopped until it ends. A surrounding temperature is measured by a temperature sensor serving as temperature measuring device, a set surrounding temperature is correlated with a set recording rate by using a data table stored in an internal memory of a controller serving as correlating device, and a recording rate is changed by a digital signal processing portion serving as recording control device on the basis of the surrounding temperature measuring result and the correlating result, wherein the recording rate is changed by changing a ratio of a recording operation time and a recording-stop operation time with alternately repeating a recording operation and a recording-stop operation at as low a laser beam output as playback.

摘要： A recording method for an optical disc drive and an optical disc drive wherein a surrounding temperature is measured by a temperature sensor serving as temperature measuring device, a set surrounding temperature is correlated with a set recording rate by using a data table stored in an internal memory of a controller serving as correlating device, and a recording rate is changed by a digital signal processing portion serving as recording control device based on the surrounding temperature measuring result and the correlating result. The recording rate is changed by changing a ratio of a recording operation time and a recording-stop operation time with alternately repeating a recording operation and a recording-stop operation at as low a laser beam output as playback.
