The bit error rate is calculated and the result is analyzed using the mean magnetization reversal number per unit time as a function of the writing time. We confirm the stochastic calculation result by employing a micromagnetic simulation. HDMR has a certain margin for erasure-after-write, since half of the writing time determined by field is for the magnetic dot and the rest is for the nonmagnetic spacing. HDMR also has a certain margin for the dot aspect ratio, since the dot is relatively large. Therefore, the combination of a small anisotropy constant and a large dot volume can be used to improve write-error. When we choose a small anisotropy constant, the mean magnetization reversal number per unit time in the opposite direction to the recording direction is negligible. Furthermore, the writing time determined by medium is longer. Therefore, the bit error rate caused by write-error is low for a small anisotropy constant.","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"}]},"item_10001_relation_14":{"attribute_name":"item_10001_relation_14","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.3379/msjmag.2409R001","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"}]},"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_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_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":"Nakatani, Yoshinobu","creatorNameLang":"en"}]},{"creatorNames":[{"creatorName":"Tagawa, Ikuya","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":"2024-10-01"}],"filename":"2024JA0008.pdf","filesize":[{"value":"845 KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"2024JA0008.pdf","url":"https://mie-u.repo.nii.ac.jp/record/2000897/files/2024JA0008.pdf"},"version_id":"6237f8b4-fcf7-40c5-8e3d-2a7c9f18bae9"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"HDMR","subitem_subject_scheme":"Other"},{"subitem_subject":"10 years of archiving","subitem_subject_scheme":"Other"},{"subitem_subject":"ATI","subitem_subject_scheme":"Other"},{"subitem_subject":"dot height","subitem_subject_scheme":"Other"},{"subitem_subject":"bit error rate","subitem_subject_scheme":"Other"},{"subitem_subject":"anisotropy constant ratio","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 Anisotropy Constant on Writability in Heated-Dot Magnetic Recording","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Influence of Anisotropy Constant on Writability in Heated-Dot Magnetic Recording","subitem_title_language":"en"}]},"item_type_id":"10001","owner":"15","path":["639"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-10-01"},"publish_date":"2024-10-01","publish_status":"0","recid":"2000897","relation_version_is_last":true,"title":["Influence of Anisotropy Constant on Writability in Heated-Dot Magnetic Recording"],"weko_creator_id":"15","weko_shared_id":-1},"updated":"2025-02-03T00:56:08.848870+00:00"}
