Magnetic drum memory or magnetic drum storage, a type of computer memory/storage that is now long obsolete.
Magnetic forces are not necessarily bad for computers, as mechanical hard disks use them to store information. However, you shouldn't place any magnetic objects near them as it will ruin your data that's store on those kinds of disks.
Any information you want.
In a cell, DNA or Deoxiribose Nucleic Acid stores and transmits genetic information.
It sounds like you might be referring to a device called a magnetic card reader, which reads information stored on magnetic stripes found on credit cards, IDs, and other types of cards. These readers use magnetic fields to interpret the data encoded on the magnetic stripe and typically interface with a computer or other device to process the information.
Electric and magnetic fields contain energy and information. They transport this energy and information through space. In the case of electric fields, they are generated by stationary electric charges and transport energy and information by interacting with other charges. Magnetic fields, on the other hand, are generated by moving charges or changing electric fields and also transport energy and information through their interactions with other magnetic fields or moving charges.
Information on magnetic cylinders, such as those used in tape drives or magnetic storage devices, is stored in the form of magnetic patterns. These patterns represent binary data, with the magnetic orientation of small regions on the surface of the cylinder indicating either a 0 or a 1. As the cylinder rotates, a read/write head detects these magnetic patterns to read or write information, allowing for data retrieval and storage. The density of these magnetic patterns determines the amount of information that can be stored on the cylinder.
Information is stored in the computer's hard drive, which is a magnetic disk read by lasers.
A magnetic stripe card contains a magnetic stripe that stores information. Unlike smart cards, magnetic stripe cards are passive devices that contain no circuits. These cards are sometimes called swipe cards: they are read when swiped through a card reader.
No. of Cylinders = No. of Tracks on each platter multiply by 2 for both sides since each platter stores information on both sides.

To find more information about magnetic notepads, one should try the local stationary store, such as Staples. Alternatively, try webpage stores such as Amazon or Ebay.
A computer's hard disk or hard drive stores information such has the operating system, programs, and files. It stores the information as small magnetic fields on the hard disc.A hard disk drive is a non-volatile storage device that stores digitally encoded data on rapidly rotating rigid (i.e. hard) platters with magnetic surfaces.

Hot water cylinders are available from stores that sell heating and plumbing supplies. Example include Heat And Plumb, Hot Water Cylinders, Discounted Heating, and Screwfix.
The magnetic strip on ATM cards is made of magnetic material that stores account information in binary code. It is typically made of a polymer material with magnetic particles embedded in it. The strip is encoded with data that can be read by magnetic stripe readers to authorize transactions.
A magnetic disk is a disk which stores information magnetically, and is read/written with a small magnetic head (e.g. a hard disk)An optical disk is a disk which stores information optically, usually as a series of pits and peaks, and is read/writMagnetic Storagea) Stores data in magnetic form & it doesn't use laser to read/write datab) It is affected by magnetic field.c) It has high storage capacity.d) Data accessing is high as compared to CD's and DVD's.e) Magnetic storage devices are ; Hard disk , Floppydisk, Magnetic tape etc.Optical Storagea) Stores data optically & uses laser to read/write.b) It is not affected by magnetic field.c) It has less storage than hard disk.d) Data accessing is high as compared to floppy.e) Optical storage devices are ; CD-ROM,CD-R,CD-RW, DVD etc.
the HDD stores all of the information for the computer
