摘要

Method for determining a first value of paru00e1metro clearing of focus to write content data into a storage medium of multilayer first unit to determine the value of paru00e1metro clearing of focus, the device initiator of storage media, a method for Write data content on a storage medium of multilayer, and computer program product.The present invention relates to a method and a unit for determining parameter (100) to determine a first parameter value of the compensation of focus.The method to determine the parameter value for write data content on a storage medium layers (114) includes the steps of writing sequ00fau00eancias test data using the first parameter values of compensation of the estimated (step 206) different focus, read Sequ00fau00eancias test data (step 206)Determine the values of at least one measure of deviation of the data from the sequ00fau00eancias test data read (step 206), and to determine the first parameter value of compensation of focus in dependence of the measured values of at least one measure of deviation of the data (steps 210, 222), such that the The error rate of the block data reading of content.Written to the storage medium layers (114) while using the first parameter value of compensation determined focus and udos of portable storage medium layers (114) while using the second parameter value of compensation determined focus is minimi Zada.
