The bit error rate is calculated and the result is analyzed using the mean magnetization reversal numbers per unit time N+ and N- for the magnetization reversal in the direction opposite to the recording direction and in the recording direction, respectively. The writing improves as the N+ value decreases and the N- value increases. The N+ and N- values decrease as the α value decreases, since the attempt frequency is approximately proportional to α. The writing time when the N- value is large is rather short compared with the writing time determined by the writing field. Therefore, a magnetization reversal time that is much shorter than the writing time is needed to write data. The 1/N- value represents the stochastic magnetization reversal time under thermal agitation, and the 1/N- value is inversely proportional to α. Although the N+ value becomes small, a small α value is disadvantageous to writing.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10001_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"公益社団法人 日本磁気学会","subitem_publisher_language":"ja"}]},"item_10001_relation_14":{"attribute_name":"item_10001_relation_14","attribute_value_mlt":[{"subitem_relation_type":"isVersionOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.3379/msjmag.2501R001","subitem_relation_type_select":"DOI"}}]},"item_10001_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"本資料の著作権は公益社団法人 日本磁気学会 (The Magnetics Society of Japan)が保有しています","subitem_rights_language":"ja"}]},"item_10001_source_id_9":{"attribute_name":"item_10001_source_id_9","attribute_value_mlt":[{"subitem_source_identifier":"1882-2924","subitem_source_identifier_type":"PISSN"}]},"item_10001_text_36":{"attribute_name":"出版者（ヨミ）","attribute_value_mlt":[{"subitem_text_language":"ja-Kana","subitem_text_value":"コウエキシャダンホウジン ニホンジキガッカイ"}]},"item_10001_text_70":{"attribute_name":"item_10001_text_70","attribute_value_mlt":[{"subitem_text_language":"ja","subitem_text_value":"Journal Article / 学術雑誌論文"}]},"item_10001_version_type_20":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_ab4af688f83e57aa","subitem_version_type":"AM"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Kobayashi, Tadashi","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Tagawa, Ikuya","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Nakatani, Yoshinobu","creatorNameLang":"en"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2025-02-03"}],"filename":"2024JA0010.pdf","filesize":[{"value":"1 MB"}],"format":"application/pdf","url":{"url":"https://mie-u.repo.nii.ac.jp/record/2001141/files/2024JA0010.pdf"},"version_id":"412ad663-dd51-442e-90dc-ff561994fa59"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"HDMR","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Gilbert damping constant","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"stochastic calculation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"micromagnetic simulation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"bit error rate","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"reversal number","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"reversal time","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"item_resource_type","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Influence of Damping Constant on Writability in Heated-Dot Magnetic Recording","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Influence of Damping Constant on Writability in Heated-Dot Magnetic Recording","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"13","path":["639"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2025-02-03"},"publish_date":"2025-02-03","publish_status":"0","recid":"2001141","relation_version_is_last":true,"title":["Influence of Damping Constant on Writability in Heated-Dot Magnetic Recording"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2025-02-03T02:40:26.137797+00:00"}
