Description
本發明係關於一種用以形成光記錄媒體之保護膜且具有高強度之濺鍍靶(以下,簡稱靶),又該光記錄媒體則可藉雷射光而進行資訊之記錄、再生、記錄及再生及消去者。
本申請案係基於2006年6月8日在日本申請之特願2006-159303號而主張優先權,該內容在本案中均加以援用。
一般而言,構成光碟等光記錄媒體之保護膜(包含下部保護膜及上部保護膜,以下同),其代表性者已知為含有二氧化矽(SiO2
):20%,且殘餘部為氧化鋅(ZnS)所成之組織;已知具有該組成之保護膜,可藉由使用:含有二氧化矽(SiO2
):20%,且殘餘部為氧化鋅(ZnS)所成之ZnS-SiO2
系熱壓燒結體所構成之形成光記錄媒體保護膜用濺鍍靶,即可製得。
然而,由該ZnS-SiO2
系熱壓燒結體所成之靶,在以雷射光照射記錄膜進行重複書寫時,ZnS-SiO2
系熱壓燒結體所成之靶中所構成之ZnS,其S卻有擴散至記錄膜中並使重複書寫之功能降低之缺點。因此,目前已經在開發不含S之保護膜,而不含S之保護膜之一個例子,以莫耳計,已知有以下者。
(i)將含有氧化鋯:10~70%、二氧化矽:50%以下(不含0%),以及殘餘部:氧化鋁及不可避不純物所成之配合組成之混合粉末加以燒結之光記錄媒體保護膜。
(ii)將含有氧化鉿:10~70%、二氧化矽:50%以下(不含0%),以及殘餘部:氧化鋁及不可避不純物所成之配合組成之混合粉末加以燒結之光記錄媒體保護膜。
(iii)將含有氧化鋯:10~70%、氧化釔:0.1~8.4%、二氧化矽:50%以下(不含0%),以及殘餘部:氧化鋁及不可避不純物所成之配合組成之混合粉末加以燒結之光記錄媒體保護膜。
(iv)將含有氧化鋯:10~70%、二氧化矽:50%以下(不含0%),以及殘餘部:氧化鑭及不可避不純物所成之配合組成之混合粉末加以燒結之光記錄媒體保護膜。
(v)將含有氧化鉿:10~70%、二氧化矽:50%以下(不含0%),以及殘餘部:氧化鑭及不可避不純物所成之配合組成之混合粉末加以燒結之光記錄媒體保護膜。
(vi)將含有氧化鋯:10~70%、氧化釔:0.1~8.4%、二氧化矽:50%以下(不含0%),以及殘餘部:氧化鑭
及不可避不純物所成之配合組成之混合粉末加以燒結之光記錄媒體保護膜。
(vii)將含有氧化鋯:10~70%、二氧化矽:50%以下(不含0%),以及殘餘部:氧化銦及不可避不純物所成之配合組成之混合粉末加以燒結之光記錄媒體保護膜。
(viii)將含有氧化鉿:10~70%、二氧化矽:50%以下(不含0%),以及殘餘部:氧化銦及不可避不純物所成之配合組成之混合粉末加以燒結之光記錄媒體保護膜。
(ix)將含有氧化鋯:10~70%、氧化釔:0.1~8.4%、二氧化矽:50%以下(不含0%),以及殘餘部:氧化銦及不可避不純物所成之配合組成之混合粉末加以燒結之光記錄媒體保護膜。
進而,用以形成前述(i)~(ix)所記載之成分組成之光記錄媒體保護膜之濺鍍靶亦正在開發中,該靶係具有與前述(i)~(ix)所記載之光記錄媒體保護膜為同一之成分組成者(專利文獻1參照)。
前述靶,係準備了前述(i)~(ix)所記載之氧化物粉末作為原料粉末,再將該等原料粉末依所定之比例配合後加以混合製作成混合粉末,並於形成該混合粉末後在大氣中或氧氣環境等之氧化性環境中加以燒結而製得。
專利文獻1:特開2005-56545號公報
然而,準備了前述(i)~(ix)所記載之氧化物粉末作為原料粉末,再將該等原料粉末依所定之比例配合後加以混合製作成混合粉末,並於形成該混合粉末後在氧化性環境中依通常條件加以燒結而製得之靶,其在高輸出功率濺鍍中會發生破裂,且無法以良好之效率形成光記錄媒體保護膜。本發明之目的,即在提供一種即使在高輸出功率濺鍍中亦不會發生破裂之形成高強度光記錄媒體保護膜用濺鍍靶。
