Abstract
(EN) A battery-operated recording medium controller monitors the ID of a replayed melody and when a replay ID comparing section (A126) makes a decision that a melody of the same ID as the previous one is replayed, a section (A127) for judging necessity of auxiliary information designates an auxiliary information access control section not to acquire auxiliary information (ID3 tag) again from a disc but to reuse auxiliary information stored in an auxiliary information storing section A. Consequently, the number of times of accessing the recording medium is decreased, and when the auxiliary information added to reproduction data like the ID3 tag of an MP3 is acquired, moving distance of an optical pickup is decreased and current consumption can be reduced.
(FR) Une commande de support d'enregistrement fonctionnant sur piles surveille l'ID d'une mélodie reprise. Lorsqu'une unité de comparaison d'ID reprise (A126) détecte la reprise d'une mélodie à ID identique à la précédente, une unité (A127) servant à estimer le besoin d'informations auxiliaires instruit une unité de commande d'accès d'informations auxiliaires de ne pas réacquérir d'informations auxiliaires (étiquette ID 3) d'un disque mais de réutiliser les informations auxiliaires mémorisées dans une mémoire (A) d'informations auxiliaires, ce qui permet de réduire la fréquence d'accès au support d'enregistrement. Par ailleurs, lorsque les informations auxiliaires ajoutées aux données de reproduction telles que l'étiquette ID3 d'un MP3 sont acquises, la distance de déplacement d'une tête de lecture optique diminue et la consommation de courant baisse.
(JA) 電池動作する本発明の記録媒体制御装置において、再生曲のIDを監視し、再生ID比較部A126が前回と同じIDの曲を再生すると判定した場合は、補助情報要否判定部A127の指示により補助情報アクセス制御部はディスクから補助情報(ID3タグ)の再取得を行わず、補助情報格納部Aに記憶しておいた補助情報を再利用する。これにより、記録媒体へのアクセス回数を減らし、MP3のID3タグのように再生データに付加された補助情報の取得を行う場合、光ピックアップの移動量を少なくし、電流消費を減らすことができる。
