Not really.
A standard plate based hard disk (as opposed to SSD) can't read and write simultaneously. However, when for example you're copying a file within the same disk, it may seem that it's being done at the same time. In reality, your HDD first loads the copied file (or part of it) into RAM and then writes it but you see only one progress bar so you may think it's simultaneous.
Sometimes you can actually spot this. If the file to be copied has been loaded into RAM before, you'll see the progress bar moving very fast and slowing down later.

How is data stored in hard disk?
To read, there are very small electric coils that sense the magnetic polarization; these coils are mounted on arms which pivot and move across and very close to the surface of the disk. (see the image link under Sources... below) These coils read the polarization which represents the 1's and 0's of the binary information stored on the magnetic disk. The write mechanisms make use of the electricity flowing through a coil in the write head that produces a magnetic field. Electrical pulses are sent to the write head, with different patterns of positive and negative currents. The current in the coil of the write head induces a magnetic field across the gap between the head and the magnetic disk platter, which in turn magnetizes a small area on the recording medium. The Read/Write head assembly works to read and write using basically the same technology, early units used the same hardware for both, modern units can have slightly different configurations of the microscopic gaps between coils and magnets etc. for optimum performance.
Winchester disk and hard disk are same or not?
Same as far as I know. Winchester was an OLD hard drive.
Can a floppy disk drive read a floppy disk regardless of how the write protect notch is set?
Yes. The write protection notch is the same for USB, floppy, and other portable media. What is is supposed to do is prevent changing of the data, not reading of the data, on the disk.
What are the similarities of a floppy disk and a hard disk?
In their basic form, floppy discs are common hard disks are the same technology. They both use magnetism to store and read data. They both use a spinning platter read by a horizontally moving read head. The key differences are that hard disks have the data and reader in the same package, this is why hard discs have evolved in storage capacity while floppy disks remained the same. It was necessary for the written layer of a floppy disk to have the same data density and dimensions as they had to be compatible with floppy disk drives. However with hard discs the drives and read heads could evolve along side the data layer. Hard discs now have metal platers, and store data at a much higher density. The speed of the mechanisms are much much faster. New technologies such as perpendicular storage can be added and have no impact on compatibility.

How do the hard disk work After replacing it?
It spins for one ( at usually 7200 rpm) and writes in a language that involves 1 and 0's(Binary Code) It is a like a rewritable CD but a lot cooler A hard disk stores data in much the same way as a floppy drive, magnetic pulses are imprinted onto the surface of the disk by a read/write head which can also then read the data back. Hard disks differ from floppies in that the data can be stored in much higher densities and accessed at much higher speeds by using a non-removable disk which is sealed from contaminants. Modern hard disks usually have several disks within them (platters) and dedicated read/write heads for both sides of each. The platters themselves are usually made of some aluminum alloy coated with a thin layer of iron oxide and are very rigid. A hard disk drive (HDD), commonly referred to as a hard drive, hard disk, or fixed disk drive, is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces. Strictly speaking, "drive" refers to a device distinct from its medium, such as a tape drive and its tape, or a floppy disk drive and its floppy disk. Early HDDs had removable media; however, an HDD today is typically a sealed unit (except for a filtered vent hole to equalize air pressure) with fixed media.
hard disk and hardware are the same?
no seriously
What does it mean when garageband says this disk is too slow?
When this error message appears, Garageband is trying to read or write audio tracks to the hard drive and cannot write or read the information fast enough. This can be caused by a very old Mac, a hard drive nearing its capacity, or a hard drive that is being used by another program at the same time. You will need to make sure that TimeMachine backup is disabled and any other applications or utilities that access the hard drive are not running when you run Garageband.
What is virtual hard disk?
Virtual Hard Disk (VHD)Those type of file are using mostly for computer emulatorsThey are the same as ZIP,RAR,ZIPX...Strong coded that only can be read from programs like Virtual PC,and of coure strong compressed.
How is information stored magnetically to the computer hard drives?
Widely used Magnetic platters Hard disk drives uses Properties of Magnetism. As known Data is stored in Binary form, the disk uses North/South Polarity created on Magnetic disk platter as 0 or 1 (binary digits). The sensor (Read/Write Head) in Hard disk senses magnetic orientation at a very small area and interprets it as Binary Digit.For storing data on Hard disk the magnetic orientations are changed according to data by Read/Write Head.
What is the difference between super disk and hard disk?
The super-disk or LS-120 and its derivatives are a removable disk more akin to a zip disk or floppy disk. They are designed to be easily swapped from machine to machine. Physically they resemble a floppy disk in that it has an internal platter is composed of flexible plastic encased in a hard case for protection. A hard disk is designed to reside permanently in the same computer and acts as the primary storage & boot device. A hard disk is a semi-sealed device inside the computer which has several rigid aluminum (usually) platters permanently encased within an aluminum shell. Hard disks can read & write data at a much faster rate than superdisks. Hard disks can store a great deal more data than superdisks. Superdisks are generally considered to be obsolete these days, with thumb drives cd-rws and dvd-rws having taken their place as easily portable storage devices.
What does it mean to over write on a floppy disk?
If the same data is already in the floppy disk or any other disk, and you are again copying the same data, then it is called the overwriting ..
