• intros：{"brand_intro":"威宝（Verbatim）创立于1969年，是美国老牌存储介质制造商，现属三菱化学旗下。作为光盘行业的\"技术派\"，威宝率先推出超硬涂层（Super Hard Coat）技术，使盘片抗刮擦能力提升10倍。其品控理念是\"零缺陷出厂\"，每批次抽检率高达30%。在专业刻录圈，威宝与索尼、三菱并称\"光盘三巨头\"，尤其受数据备份发烧友青睐。","product_intro":"威宝超硬系列DVD-RW主打耐用性和性价比，5片装售价约45元，单片仅9元。核心卖点是独家超硬涂层，可抵抗日常划痕和指纹，适合频繁取用的场景。相比普通RW盘，其记录层采用AZO染料（威宝专利），数据保存寿命长达50年。竞品对比中，威宝的写入速度支持1-4倍速，但实际兼容性略逊于索尼，部分老刻录机需降速使用。","key_specs":{"存储容量":"4.7GB，约120分钟视频","擦写次数":"标称1000次，实测约700-900次","写入速度":"1-4倍速，推荐2倍速刻录","涂层技术":"超硬涂层（Super Hard Coat），抗刮等级8H","记录层材料":"AZO有机染料+相变层"}}
