吾人得知,自資訊層堆疊中除去金屬鏡層不僅造成資訊 層之光學行為之後果’並且其熱特性亦有影響。金屬具有 較干涉層及相位改變層為高之熱傳導率。金屬鏡層熱傳導 率對非晶記號之實際寫入方法上為一優點。在窝入方法期 間,相位改變材料由寫入脈波加熱至數百攝氏度。結果, 相位改變材料被迅速冷卻以防熔化(即非晶)材料之再晶體 化。欲使此方法成功,冷卻時間必須較再晶化時間為短。 金屬鏡層之大熱傳導率及熱容量可協助自熔化之相位改變 材料迅速移除熱量。但,在一(半)透明資訊層,具有或無 降低量之此種冷卻金屬鏡層,冷卻時間似乎較使相位改變 材料再晶化之時間為長。因此導致標記之低品質。 本發明之方法可使在窝入脈波順序中之二連續寫入脈 波間之冷卻期間較長。此舉可增加冷卻時間因而導致良好 品質之標記。 以此知名方法,具有時間長度為nT之標記由包含n_2及 η-1寫入脈波之窝入脈波順序予以記錄。特別為較長標記而 言’此舉可導致一大量數目之窝入脈波,結果,大量之熱 被積聚在相位改變層,在寫入脈波之間無冷卻之可能。但 ,在本發明方法之實施例中,其中之寫入脈波(m)設定於最 接近η/ α (m21)之接近整數,寫入脈波之數目可降低,導致 寫入脈波間之冷卻時間大幅增加。 在此方法另一實施例中,寫入脈波(m)之數目設定等於最 接近整數,其大於或等於n/a(m2l)。 設定α為2之值可獲得良好之結果。在本發明方法之較 -6- 本紙張尺度適用中國國家標準(CNS) Α4規格(210X297公复) 1226054 A7 —---- B7 五、發明説明(4 ) 佳實施例中可獲得近一步之改進,其中之α設定之值為3 ’導致在寫入脈波順序中之寫入脈波間之冷卻間隔較長。 在本方法之此實施例中,一 6丁標記利用寫入脈波順序記錄 該寫入脈波順序僅含二寫入脈波,而在已知方法中,脈波 順序將包含4(η_2)至^心丨)寫入脈波。 當一^標記由m寫入脈波順序記錄時,m為大於或等於 Π/α<最近整數,“不同標記長度由寫人脈波順序中之相 同數目寫入脈波加以記錄。例如,當α設定為3,4Τ,5丁 及6Τ標記均由2寫人脈波之順序加以記錄。因&,必須有 寫入脈波之額外精細調譜。在本發明方法之實施例中,在 順序中”少一窝入脈波之位置之設定與η有關。在本發明 方法另-實施例中,順序中至少一寫入脈波之期間之設定 與η有關。 上述之與η相關調整參數(即,脈波位置,脈波功率,脈 波寬度)僅能應用於單-參數或此等參數之任何組合。此外 ’此等參數可為窝人脈波順序中之單—脈波調整,亦可為 脈波順序中之數個脈波調整。 當毕值寫人功率位準受到限制時(由於輕射源或記錄載 體所加之限制),調整脈波寬度以獲得較長之寫入脈波,因 而增加總寫入功率實為-優點。使用較長脈波寬度之能力 通常可利用較低輕射功率β 應注意’本發明方法可優異地使用於任何高速光學記錄 系統,其使用相位改變型單資訊層或多資訊層之記錄載體 而冷卻時間甚重要時尤甚。在此系統中,記錄期間之冷卻 本纸張尺度適用中國國家標準(CNS) Α4規格(210X297公釐)----------
