Please contact Media Sciences if your questions are not answered on these pages. Such problems may occur only after 60 or 70 minutes of recording. Problems at 1X might only be observed with certain models, and then only for some drives of that model number. Repair and recalibration of a problem drive will often fix the 1X problem.
High speeds generate high frequency vibrations.
1X recording speeds produce lower frequency vibrations that might interfere with low frequency servo loops. Also, recording power does not increase linearly with speed, therefore higher speed recording can reduce the total energy required for recording. This may reduce thermal drift in the optical head. Recording drives should be tested at all recording speeds and at full disc capacity. Problems at one speed point to a flawed writer that should be repaired or replaced.
