VERFAHREN UND VORRICHTUNG ZUR HERSTELLUNG EINES MAGNETISCHEN AUFZEICHNUNGSMEDIUMS
摘要
<p>A method and apparatus for coating a magnetic liquid onto a moving substrate to form a magnetic recording medium having an improved product yield and reduced streaking. Coating liquid is fed to an extruder by a second pump, while excess coating liquid is extracted from the extruder and returned to a storage tank with a second pump. When the coating operation is to be stopped, the extruder is bypassed between the first and second pumps and a portion of the output from the first pump is returned directly to the storage tank so that the flow rates through both pumps are the same during coating and idling times.</p>
