In-Depth Information
The.biggest.problem.with.recovering.or.acquiring.data.from.
one.of.these.types.of.media.can.be.the.lack.of.the.correct.drive.
or.device.that.will.access.and.read.them,.especially.as.you.con-
sider.the.older.and.rarer.varieties.of.loppy.disk.media..If.you.
ind.that.you.need.to.gather.data.from.one.of.these.types.of.
media,.it.will.require.that.you.contact.someone.with.the.cor-
rect.drive.to.access,.read,.and.preserve.that.information.
Tape.drives.simply.use.magnetic.tape.that.is.spooled.and.
runs.past.read-write.pads..Those.pads.pick.up.or.lay.down.
the.magnetic.pulses.representing.the.ones.and.zeros.of.data.
onto.the.tape..They.can.be.overwritten.and.used.more.than.
once,.though.they.do.suffer.from.damage.and.wear.and.tear.
more.than.the.other.media.we.discussed.so.far.
Magnetic.tape.reels.were.used.as.one.of.the.irst.ways.to.
store. large. amounts. of. data. long. term. in. the. early. days. of.
computing..You.may.even.have.seen.old.movies.where.there.
were. giant. computers. with. spinning. tape. reels.. These. can.
still.be.found.in.large.data.centers,.though.the.more.common.
use.of.magnetic.tape.is.in.small.cartridges.that.are.used.for.
backup.storage.
These.can.be.hugely.important.resources.for.archival.data.
and. should. deinitely. be. considered. when. you. are. thinking.
about.where.data.might.live..But.as.mentioned.above,.they.
can.be.corrupted.or.worn.out,.so.again.they.may.require.spe-
cialists.to.recover.data.from.them.
Finally,.we.come.to.the.type.of.storage.that.is.fast.becom-
ing.the.norm:.solid-state.or.lash.memory..This.type.of.mem-
ory.has.been.around.for.a.long.time.in.places.like.the.BIOS.
chip.on.the.motherboard.of.a.computer,.or.in.those.small.SD.
cards.used.in.cameras.
This.technology.has.evolved.as.well.and.many.of.the.new.
smart. phones,. tablets,. laptops,. and. so. on,. are. now. using.
this.type.of.storage.because.it.is.fast,.small,.lightweight,.and.
uses. less. energy. and. generates. less. heat. than. conventional.
mechanical.storage.
Flash. or. solid-state. memory. uses. a. technology. known.
as. EEPROM,. which. stands. for. electronically. erasable.
