盒式录音磁带(包括空白带和有声带)是把磁带、供带盘、收带盘都置于一个塑料盒内的组合体.磁带由两层构成,厚度只有9-18微米,一层是基片,通常用聚酯薄膜制成,一般为白色透明体,用于承载磁性层.另一层是磁性层,由磁粉加入润滑剂、分散剂、抗静电剂、增塑剂等助剂与粘合剂混合制成的磁浆,涂布在基带上,经微粒定向、烘干、压光、切割等工艺而制成。
Cassette tapes (including blank tapes and vocal cords) are tapes, tape reels, and take-up tapes housed in a plastic box. The tape consists of two layers of only 9-18 microns in thickness and one The substrate, usually made of polyester film, is generally a white transparent body for carrying a magnetic layer, the other layer is a magnetic layer, and the magnetic powder is added with additives such as a lubricant, a dispersant, an antistatic agent, a plasticizer and the like Adhesive mixed magnetic slurry, coated on the baseband, the particles orientation, drying, calendaring, cutting and other processes made.
