Abstract
本発明の研磨基材10は、可撓性基材20と、可撓性基材20における一方の面に形成され、可撓性基材20よりも弾力性に富む材料からなるクッション層30と、クッション層30上に形成されたナノ繊維層40とを備える研磨基材である。 本発明の研磨基材10によれば、従来よりも微細な研磨材を用いて磁気記録媒体におけるテクスチャ加工を行うことが可能になるとともに、研磨基材として十分な機械的強度を確保することが可能となり、もって、磁気記録媒体におけるテクスチャ加工を従来よりも高精度に行うことが可能となる。また、本発明の研磨基材10をワイピング用の基材として用いれば、磁気記録媒体におけるフィルムクリーニング処理又はバーニッシング処理を従来よりも高精度に行うことが可能となる。
