Yes, they ARE magnetic
Neither. They are removable magnetic storage. Optical storage consist of CDs, DVDs, etc.
A magnetic tape cartridge is neither RAM (Random Access Memory) nor ROM (Read-Only Memory); it is a form of storage media. Magnetic tapes are used for data storage and retrieval, functioning as a sequential access storage medium. Unlike RAM, which is volatile and used for temporary data storage, or ROM, which is non-volatile and permanently stores firmware, magnetic tapes are primarily used for backup and archival purposes.
A hard disk drive is a type of magnetic storage device. A magnetic storage device stores data on a magnetized medium. Other types of magnetic storage includes magnetic recording tapes and the stripes on credit cards.
Magnetic tapes are usually used for data storage. The length of a magnetic tape is 10.5 inches

Primary storage refers to the main memory of a computer, such as RAM, which is fast but temporary and volatile, meaning it loses data when power is off. Secondary storage, like hard drives and SSDs, is non-volatile and provides long-term data storage, retaining information even without power. Offline storage refers to any storage that is not directly accessible by the computer's operating system, such as external hard drives, USB drives, or magnetic tapes, which can be disconnected and used for backup or transfer purposes. In summary, primary storage is fast and temporary, secondary storage is slower but permanent, and offline storage is external and not directly connected to the system.
There are primarily two types of magnetic tapes: analog tapes and digital tapes. Analog tapes store information using varying magnetic fields and were commonly used for audio recording. Digital tapes store data in binary form and are used for data backup and archival purposes.
It varies from few Gbs to Tbs based on the size and type of tape. Magnetic tapes were storing more than 5Tb of data on single tape. Oracle's Storage Tek tape offers 5 Tb of storage space
Two storage devices that use a magnetic medium for storing data are hard disk drives (HDDs) and magnetic tapes. HDDs utilize spinning disks coated with a magnetic material to read and write data, making them suitable for large-scale storage in computers. Magnetic tapes, on the other hand, are often used for archival purposes and backup, storing data sequentially on a long strip of magnetically coated plastic. Both devices leverage magnetic properties to achieve data retention and retrieval.
Permanent storage mediums are devices or technologies used to store data indefinitely without the need for power. Common examples include hard disk drives (HDDs), solid-state drives (SSDs), optical discs (like CDs, DVDs, and Blu-rays), and magnetic tapes. Additionally, cloud storage can also serve as a permanent solution when data is redundantly stored across multiple servers. These mediums are designed for long-term data retention, ensuring accessibility over time.
