Claims5
A magnetic drum/head system for reproducing a recorded information, comprising a magnetic drum cassette having therein a magnetic drum driven by a capstan, a magnetic head contacting an information track on the magnetic drum for generating selected recorded information, wherein said magnetic drum cassette comprises:
- a lower casing having a bearing at its central portion;
- an upper casing fitted to said lower casing to form a housing for enclosing therein said magnetic drum;
- an oil coating device mounted on resilient means fixed to said housing to slidably contact with the circumference of said magnetic drum;
- an opening in said housing for permitting said magnetic head through said opening;
- and,
- a cover, slidably mounted on means formed on said housing, for opening and closing said opening in the housing, thereby protecting said magnetic drum when said cassette is released from said system;
- wherein said cover has a cleaner plate for cleaning said magnetic head when said cover is repeatedly slid manually in and out of contact with the magnetic head.
