Which method is used to destroy laser disc medical records?

The most effective method for destroying laser disc medical records is pulverizing. This process involves reducing the material to a fine powder, ensuring that the data contained on the disc is completely irretrievable. Laser discs often have a coating that can protect the data from common destruction methods, requiring a more thorough technique like pulverizing.

Other methods, while they may provide some level of destruction, might not guarantee complete data destruction. Shredding, for instance, is more effective with paper documents and may not adequately handle the unique materials of laser discs. Demagnetizing is specific to magnetic storage media and would not apply to laser discs, which do not store data magnetically. Recycling is a method of disposing of materials but would not ensure that the sensitive health information contained on the discs is destroyed, leaving a risk of data recovery. Thus, pulverizing is the most appropriate and secure choice for ensuring total data destruction on laser disc medical records.
