A Brief History of IPOD
Author: By: Roberto Sedycias
iPod is a digital mp3 / mp4 player developed and marketed by Apple Inc., an
American consumer electronics multinational corporation. During their research,
Apple found that in comparison to available camcorders, digital cameras, and
organizers; digital music players recorded poor sales, primarily due to their
awful user interfaces. Apple wanted to do something about it and so Jon
Rubinstein, Apple's hardware engineering chief brought together a team
comprising of Tony Fadell (who dreamed of a hard disk based music player),
Michael Dhuey (hardware engineer), Jonathan Ive (design engineer), and Stan Ng
(marketing manager). In less than a year, they designed a hard disk based music
player, that had a 5 GB hard drive and capable of storing 1000
songs.
Apple's iTunes software is utilized to operate the iPod (m3 / mp4
player). The software is compatible with all Mac systems. The operating system
is stored on its hard disk. A boot loader program is contained in a NOR flash
ROM chip (either 1 MB or 512 KB) which instructs the device to load the
operating system from the hard disk. The iPod has a 32 MB of RAM, a portion of
which is used to hold the operating system from firmware, and the rest is used
to cache songs from the hard disk. Apple also invented a technology whereby the
hard disk of iPod could spin up once and about 30 MB of upcoming songs could be
cached into the RAM. This did not require the hard disk to spin up for every
song and thereby saved battery power. Apple also introduced a Windows version of
iPod, at a later stage.
The audio files that iPod (mp3 / mp4 player)
supports are MP3, AAC/M4A, Protected AAC, AIFF, WAV, Audible audiobook, and
Apple Lossless audio file formats. MIDI and WMA files can be played only after a
convertor accomplishes conversion, for non-Digital Rights Management (DRM). Ogg
Vorbis, FLAC, and other open-source audio formats are not supported at
all.
Apple wanted an extremely user friendly interface and thus adopted
the minimalist interface, which features only five essential buttons, namely,
Menu (to access functions and to toggle the backlight); Center (for menu item
selection); Play/ Pause (this also works as an off switch when held for few
seconds); Skip Forward/ Fast Forward; and Skip Backwards/ Fast Reverse. An
additional Hold button is provided for accidental button pressing prevention,
and it can reset the iPod if it has frozen or crashed. Functions such as volume
control, scrolling are handled by the usage of the rotational click wheel. Later
models have some minor changes in the functions of the buttons but overall the
number of buttons has remained at five.
To market this path-breaking mp3
/ mp4 player, they needed a suitable futuristic name and so they hired a
freelance copywriter, Vinnie Chieco, and other writers to give a name. Inspired
by the movie 2001: A Space Odyssey and the dialogue "Open the pod bay door,
Hal!" with reference to the context of the Discovery One spaceship and its white
EVA Pods, Vinnie Chieco proposed the name of the product as iPod. The management
of Apple accepted the proposed name and on 23 October 2001, the iPod was
officially launched. The rest they say is history.
To enable customers to
access songs of their choice, Apple opened up an online media store The iTunes
Store on 29 April 2003, where individual songs could be downloaded at prices
less than a U.S. dollar per song. The purchased songs can be played only on
iPods. Subsequent versions of this iPod (mp3 / mp4 player) also featured video
capabilities, and thus iTunes Store started selling short videos from 12 October
2005. From 12 September 2006, full-length movies were also available at the
iTunes Store.
iPods have come a long way from their inception, and now
the latest fifth generation iPods possess multimedia capabilities and are
available in both Mac OS and Windows OS versions. Usually, if a new iPod is
plugged into a Mac OS computer, then the hard disk of this mp3 / mp4 player is
formatted as per the HFS+ file format, and if it plugged into a Windows OS
computer, it is formatted as per the FAT32 file format. From being a digital
music player, the iPod has now transformed into a digital media player.
