Summary: | To provide a detection device, an inspection device, a magnetic tape cartridge, a magnetic tape, a magnetic tape drive, a magnetic tape system, a detection method, an inspection method, and a program capable of detecting a servo pattern signal with high accuracy.SOLUTION: A detection device includes a processing device and a storage medium. The processing device stores a result of reading a reference servo pattern 52 by a servo reading element SR in the storage medium as an ideal waveform signal, acquires a servo band signal which is a result of reading a servo pattern recorded in a servo band SB by the servo reading element, and detects a servo pattern signal which is a result of reading the servo pattern by the servo reading element by comparing the ideal waveform signal with the servo band signal. The reference servo pattern is recorded between a BOT section 31A and an EOT section 31B in a longitudinal direction of a magnetic tape MT.SELECTED DRAWING: Figure 12
【課題】サーボパターン信号を精度良く検出する検出装置、検査装置、磁気テープカートリッジ、磁気テープ、磁気テープドライブ、磁気テープシステム、検出方法、検査方法、及びプログラムを提供する。【解決手段】検出装置は、処理装置と、格納媒体と、を備える。処理装置は、サーボ読取素子SRによって基準サーボパターン52が読み取られた結果を理想波形信号として格納媒体に格納し、サーボバンドSBに記録されたサーボパターンがサーボ読取素子によって読み取られた結果であるサーボバンド信号を取得し、サーボパターンがサーボ読取素子によって読み取られた結果であるサーボパターン信号を、理想波形信号とサーボバンド信号とを比較することで検出する。基準サーボパターンは、磁気テープMTの長手方向においてBOT区間31AとEOT区間31Bとの間に記録されている。【選択図】図12 |
