Abstract

Optical disk systems are still widely used in players in consumer electronics and automotive applications, although more and more audio and video contents are played from other medias such as flash memory and hard disk drive based devices. There are various architectures with the integrations of audio and video (A/V) decoders and optical disk servo components to reduced product BOM cost. Some issues are addressed for designing optical disk playing modules into an audio or video products. Servo implementation including tracking, seeking and rotating control needs to consider the characteristics of low cost mechanisms and non-ideal disks. When optical disk systems are used in portable or moving environments, the approaches from servo control side and electronic can be helpful for anti-shock. Special handlings to defect disks are important to playability.
