Magnetic recording medium production apparatus, magnetic recording medium production method, and varnishing device

A magnetic recording medium production apparatus comprising:

• a film deposition device configured to form at least a magnetic recording layer and a protective layer on a substrate, formed in an order of the magnetic recording layer followed by the protective layer;
• a lubricant application device configured to form a lubrication layer by applying a lubricant on the protective layer formed by the film deposition device;
• a varnishing device configured to perform a varnishing process, with a polishing material, on a surface of the lubrication layer applied by the lubricant application device;
• a processor;
• and
• a memory that includes instructions, which when executed, cause the processor to execute:
• collecting data on a load amount during the varnishing process;
• storing the collected data on the load amount;
• performing an operation by using the stored data on the load amount;
• and
• issuing an alarm of an abnormality of the film deposition device or the lubricant application device based on an operation result obtained by performing the operation.

A magnetic recording medium production method comprising:

• forming at least a magnetic recording layer and a protective layer on a substrate, formed in an order of the magnetic recording layer followed by the protective layer;
• forming a lubrication layer by applying a lubricant on the formed protective layer;
