An issue facing shared read/write player hard disc drives (HDDs) is when a head-media contact event occurs, any resulting plume of debris caused by the contact event not only affects the magnetic disc currently being read or written, but other magnetic discs within the HDD enclosure. The presently disclosed technology is directed as mitigating the potential consequences of such a head-media contact event. By providing one or more internal access doors within the HDD, a magnetic disc currently being read from or written to may be physically isolated from other magnetic discs within the HDD. As a result, in the event of a head-media contact event, any resulting plume of debris caused by the contact event only affects the magnetic disc currently being read or written. The remaining magnetic discs within the HDD are isolated from the plume of debris.
