Vibration-resistant playback device

摘要

A method and an arrangement for a vibration-resistant playback device, in which uninterrupted and undisturbed reproduction of information is assured despite vibrations, by use of a "shock-proof memory" by arrangement of a buffer between an EFM demodulator, and a de-interleaving and error correction unit, which provides the digital audio information. The buffer can be made of an ARAM (audio RAM), which is less expensive than a DRAM. The ARAM can be partially defective, and its use is made possible by the arrangement before the error correction unit. Subcode information is preferably used to synchronize the data in the buffer following an interruption.
