Abstract

The rotational speed of some optical disc drives (ODDs) has recently exceeded 15,000 rpm due to demand for high data-transfer rates. At these high speeds, the guide feeding system must maintain control over the optical pickup under hard acceleration and deceleration in random access operation for both read and write processes. In this paper, an advanced guide feeding system of an optical pickup for ODDs is proposed. Here, we report an advanced guide feeding system of the optical pickup for ODDs. The spring and guide feed was replaced with a nut-type guide feed. Dynamic simulations were carried out to investigate the performance of the system. A finite element method shock analysis was also carried out to assess the robustness of the system. A guide feeding system was designed based on these simulated data, considering the torque applied to a stepper motor and the maximum transmitted acceleration to the optical pickup. The advanced system was fabricated and tested under various conditions. The system was fabricated and tested under a range of different operating conditions. Tooth-jumping and step-out were eliminated and the maximum data transfer rate increased by 39.2 %.
